How to Make a Video Calling App for Android and iOS in 2022

A person visually absorbs about 85% of the information about the surrounding world. Visual perception is something that you can use now as an advantage in business. Trends show a steady increase in interest in video chats, the popularity of which among millennials already exceeds the text counterpart.

Video chat is not only preferable for communication but also finds successful use in business processes. Bring this text into focus from the right angle and continue reading the article to learn how to make a video chat app.

Best existing examples of video chat apps

In most cases, video chat apps are instant messengers that use high-quality video recording capabilities. These include WhatsApp, Instagram, and many others. At the same time, there are pure video chats that do not have text messaging. Among them are Google Duo, FaceTime, and others. We provide a list of the most popular applications as of 2022 with a video conferencing feature.

Skype

Created in 2003 and 8 years later bought by Microsoft for $8.5 billion, Skype is one of the most famous video chat apps. With more than 300 million users per month, the messenger makes money on the commercial licensing, subscription, and prepaid credits that allow contacting non-users. Microsoft does not unveil the exact amount. Among its main advantages as video chat applications:

• video conferencing with up to 25 people;

• the ability to call any device (Skype, landline, mobile phone);

• exchange of multimedia, text and voice messaging, sharing highlights of the day.

Skype was one of the first messengers with free voice/video communication that focused on the broadest audience, which allowed it to become one of the leading players in the market.

Zoom

The modern leader of the video chat market, Zoom was released back in 2013 but reached a peak in popularity during the COVID-19 pandemic. The free version of the app has a 40-minute conference feature of up to 100 participants, screen sharing, encryption, and live annotations. However, you can purchase plans starting at $149.90 per year so that you can bypass the 40-minute time limit for conferences in the free version.

Zoom has several unique features that increase the experience of using the application:

• virtual backgrounds, which were initially popularized by Zoom;

• beauty mode during video calls;

• gallery view with up to 49 open windows on one screen at a time.

Not surprisingly, Zoom made an incredible leap in popularity and profit in 2020, quadrupling its revenue twice to $328 million, marking an increase of almost 170%.

    

Google Duo

Released in 2016, Google Duo abandoned text chat and other related attributes of instant messengers, focusing on video calls. Keeping simplicity like Zoom, the application has overgrown with new features every year:

• HD 720 video quality;

• Knock-Knock function, allowing you to see the caller before the start of the conversation;

• WebRTC optimization for stable operation with low internet;

• Deep integration with Google services.

Like other Google products, Google Duo is free of charge. An example of such heavyweight players as Google creating video chatting apps allows us to notice a tendency in shifting from text to video format communication.

    

These examples show how such applications have changed over time. Now let’s look at what functionality you should add to build a video call app of high quality.

List of video chat applications features

This section opens before us a list of must-have features that you should implement to create a video chat app in 2022. Acquiring features listed above, your application will efficiently perform its primary task and corresponds to the spirit of its time:

Simple Registration

Convenient and simple registration is a pleasant greeting of guests standing at the threshold of your application. Make sure that users do not have problems with it by giving them a choice between sign-up via social networks or short manual registration.

User Profile

After the registration, your users’ identities become profiles with all known data, avatars, network status, and customization possibilities. When creating a user profile, do not overload the screen with information, allow leaving some data private, and add an online/offline status display.

Profile Management

To enable users to interact with each other, you should develop a simple app permissions system so that chat room creators have admin rights in their possessions. For messaging app where there are groups and a complex system of roles, we recommend using such access control methods as RBAС (Role-Based Access Control) for chat groups and HRBAС (Hierarchical Role-Based Access Control) if you want to provide some advanced options for a business audience.

Voice and Video Calls

Without this feature, you can not create a video calling app. To establish it, you will need a Publisher-Subscriber pattern, whereupon the WebRTC protocol is used, involving VoIP technologies: Signaling, STUN and TURN servers. These technologies establish a P2P connection. While using WebRTC, you can create video and audio communication through it.

Group Calls

This feature is a must-have for every group video chat app since it allows creating and inviting users to groups for communication in a specific circle of people. It is achieved through VoIP (Voice over Internet Protocol) technology. You are free to choose how many conference participants can interact simultaneously, but, on average, the number varies between 5 and 25.

    

Push notifications

This essential feature for any live chat app informs users about new messages or any other changes in the chat. To implement this function, use the API of the appropriate operator: Google, Amazon, Apple.

Cloud Synchronization

Storing files in the cloud will protect data in case of breakdowns of the physical device and support changes on all devices in the current state. Cloud synchronization will help maintain the app functionality even offline with a weak Internet connection, which will definitely appeal to every user. To implement this feature, you can use the highest quality platforms — Amazon Web Services and Google Cloud Platform.

Screen sharing

The ability to share a screen with other people and watch their screens significantly increases collaboration possibilities and effectiveness. For business purposes, screen sharing allows employees to share graphs, diagrams, and software demonstrations without leaving the room. You can make a video chat app with paid screen sharing, but mostly it comes into the standard functionality.

    

Encryption

End-to-end encryption has become the security standard of recent years. It encrypts messages in such a way that their content cannot be read even if your application is hacked. The addition of this feature guarantees the confidentiality of information in your video chat. Use the AES-256 protocol to secure the application by breaking the data into 256 bits and encrypting it.

Entertainment features

Today’s popular video chat applications are increasingly using emojis, stickers, virtual backgrounds to increase user retention. Statistics speak in favor of these features: more than half of the world’s users are under 30 years old, and they choose visual elements as their favorite means of expressing emotions in communication. Today custom stickers and virtual masks are also commercially profitable options: you can create a video chat app and collaborate with well-known third-party companies to embody their attributes and characters in it.

After you have decided on a list of features, the question arises of how to implement them, in other words, build a video chat app. Our next section will help you with that.

How to make a mobile video chat app: crucial steps

To smooth your road of making a video chat app, we have compiled a list of crucial steps in which we touched on both general development rules and its planning, as well as specific characteristics of our company.

The idea is the first thing that you really need

When forming an idea of the video calling app development, you should conduct thorough research and market analysis. Consider potential competitors and the state of the market — it is saturated with identical products and does not leave a chance even for a high-quality but not conspicuous product.

Only then should you proceed to the next stage of Product Strategy, which helps set the necessary accents and relate the theoretical and practical stages to build a video call app.

Product Strategy and Target Audience determination

Product Strategy is a high-scale product development plan that covers not only the technical side but also marketing, sales, and all other aspects. If you ask yourself how to build a video chat in Android and iOS, then Product Strategy will be its first step.

It begins with identifying the target audience: you have to pinpoint why and who needs your product? The first focus should be put on the millennials because the instant video chat format suits them like no other. After that, it makes sense to divide them into groups of interests.

The next step is Product Strategy practical realization: we advise you to contact the full-cycle development company to compile a full-fledged business analysis (BA).

In addition to BA, the Statements of Work (SoW), Technical Specification, and roadmap are included in the process of your app creation.

    

The roadmap is a strategic document that manipulates sets of features and has the form of a graph with markups for months/quarters. It is carried out by the client but is agreed with the vendor in terms of content and deadlines, after which it must be strictly observed. To make a live video chat app on time, we advise you not to set specific dates but to select weeks or months and highlight critical dates.

When we at Aimprosoft work with a roadmap, we put special attention to:

• Features implementation;

• Embrace of changes based on user’s feedback;

• Planning content for future updates;

• Post-launch support and bug fixing.

We suggest listening to the user’s feedback at the stage of MVP and beta testing, which will modify the roadmap.

Now, let’s move closer to the next crucible step, which is the choice of a mobile platform.

Choosing a mobile development platform

Nowadays, it is a market of two platforms covering 99% of the market. Let’s look at both options and decide which OS is best suited to develop a video chat app.

Android video chat app development

Android has already captured over 85% of the market and continues to stretch green miles worldwide. However, there are certain aspects you should take into consideration while asking yourself how to develop a video chat application in Android:

• • Work on multiple devices. The number of supported devices provides Android a colossal prevalence. Android OS is supported on smartphones, tablets, TVs, watches, so you will get access to the largest audience possible. Widespreadness lets you build a video call app and use multiple channels to increase sales and profits.

  • Google Play Marketplace. Being the most popular app store in the world, it dominates both in number (2.1 million) and in downloads (75.5 million) of applications. The key markets for Google Play are Asia, India, and the United States. Google Play’s quick automatic check of your app and lower approval requirements significantly reduces the TTM (Time to Market) and allows you to release it much faster than the App Store.

  • A large pool of skilled developers. Android apps are developed using one of the most popular programming languages in the world, Java, which removes problems with finding developers and lowers the entry threshold for all enthusiasts. Another language used for Android video chat app development, Kotlin, grows more and more with every year, promising to become even more popular someday.

    

• Official Google support. Google is constantly working on improving current software development tools, so using Android does not threaten you with a poor ecosystem. With Google support, your app will get SEO advantages over competitors, such as increased traffic, access to a variety of channels, and simplified integration with Google services. It gives your app a large marketing boost and higher revenue.

We have already discussed Android video chat app development advantages, but it is necessary to touch on its drawbacks to form a complete picture.

• Security problems

  This issue is a consequence of the open source nature of Android. Having deep access to the insides of the OS, attackers carry out malware, MITM (Man-in-the-middle), phishing, and cryptojacking attacks on millions of devices every month. Despite the constant security updates from Google, these are developers who have to devote a lot of time to protecting users through encryption, implementing additional security measures and storing confidential data.

• High OS and device fragmentation

  The mass distribution of Android negatively affects apps testing and optimization, and that is something you should be aware of when thinking about how to develop a video chat application in Android. Customization is complicated by dozens of different OS versions, which stipulates from the support of hundreds of devices with various metrics and hardware options. There are several ways to deal with this issue: decrease the device support or reduce the overall quality of the application, thereby minimizing the differences between devices.

• Users spending habits

  Statistics are ruthless: App Store earns as much as 60% more from in-store purchases. So while entering the Android market, you need to consider the reluctance of users to pay for apps and look for other ways to monetize them. The fact that 98% of the earnings come from free apps make you think about how to use this statistic in your favor.

To finally answer how to create a video chat app, we need to introduce its tech stack.

Tools and tech stack

As you can see from the table, the standard languages for Android video calling app development are used with Android SDK, Android Studio, and several video chat tools. WebRTC (Web Real-time Communication) is a common option to build a video calling app that is used to establish video communication between two or more users in both iOS and Android applications. This video chat protocol will be discussed later, but for now, let’s examine the full feature and tech stack of another platform to give you a long-awaited answer of how to build a video chat app on iOS.

Create a video chat app on iOS

Quality, not quantity — iOS is guided by this slogan in a contest with Android. Where a more popular competitor cannot be successful, Apple devices have such clear advantages:

• Device optimization

  Apple personally supports the hardware and software optimization of its devices. This allows you to develop applications for iPhone with high standards of performance and UI/UX requirements, which have become an integral part of the Apple brand and services.

• High security

  Malware, viruses, and other external threats do not endanger OS owners since Apple creates a reliable shield from the mix of the security model and the constant patches release. In addition, online transactions are encrypted in iOS, protecting against phishing and hacking.

• Low fragmentation

  Apple has only several dozen devices running iOS on the market, so developers are much easier to write and test applications. Minimal differences in OS versions accompany low device variability. Consequently, the release time is accelerated, and you can start to receive benefits as quickly as possible.

• User-friendliness

  Traditionally, even with the release of new devices on iOS, most of the functionality remains unchanged from model to model. Moreover, the design approach continues to improve, which is reflected in improving the quality of UI/UX and increasing ROI.

    

The App Store earned 47 billion in 2018, and by 2023 an increase of 120% is expected. Unlike Android apps, whose ROI is no more than 10%, iOS products confidently pay off due to the broad reach of the business audience, high-quality services, and brand visibility in general. However, high ROI, security, and ease of development do not equal perfection. To confirm these words, let’s take a look at the list of iOS drawbacks:

• Close source

  Apple wants to control the ecosystem of iOS, so the company produces its own hardware. There are two sides to that coin: low fragmentation is achieved, but the customization range is limited, tailoring the design of all applications to a standardized format.

• Long review process

  A thorough and longer review process of new apps in comparison with Google Play is a famous issue of the iOS deployment process. What it takes for Google a few hours, for Apple takes a couple of days.

• Inflexible platform

  When working with Apple products, it is worth accepting the fact that developing a UI will have little space for changes. It’s Apple’s fair price for a premium product — they sacrifice flexibility for UX and performance.

• Large app size

  In recent years, another problem of the iOS platform has appeared that is associated with the growth of the app’s weight. This problem is formed from the lack of a memory card slot and a competitive market environment. As a result, developers have to devote more time to the optimization process.

    

Having examined the features of the iOS platform, let’s move on to its technical content and see what technologies will help you with the most vital question — how to create a video chat app?

Tools and tech stack

iOS development doesn’t differ from Android in terms of video conference app development. However, as you can see from the table below, the native approach requires an entirely different set of tools.

Now, when the overall picture is formed, we suggest you follow all the stages of the video chat app development to get a complete picture of how your project will unfold.

Prototyping

In mobile app development, prototyping is the starting point of the design that allows you to think through the product’s appearance and interactions. It enables you to consider the video player’s future look, the structure of the interface, and usability while you are calling in a video chat app. These errors will be much more troublesome to fix during the UI/UX phase.

Usually, prototyping is carried out along with wireframing and is divided into 3 stages:

• conceptual;

• interactive;

• animated.

If the conceptual stage can be carried out using a whiteboard with markers, then for interactive and animated you will need special tools that allow designers to simulate a look, test performance, and improve UX without writing a single line of code. We have selected for you the best four of them:

InVision

Top prototyping application that receives constant updates with the addition of new functionality. InVision provides deep opportunities for workflow, offering such features as Smooth Management and Real-time collaboration between the team.

Principle

This tool is one of the best choices for prototype visualization. Despite the lack of functional options for collaboration, Principle remains the finest solution for presentations to the client with advanced animation capabilities. The license costs $129 and only supports macOS.

Proto.io

Browser-based solution Proto.io does not require special coding skills and is suitable for both beginners and experienced designers. The tool features intuitive logic and a convenient interface, allowing you to change the static design to a digestible attractive prototype in a matter of minutes.

    

Axure

On the opposite side of the complexity spectrum is Axure, an advanced and over-featured prototyping tool that requires a wealth of code knowledge from the designer to cope with it. Axure allows you to set interactions and style effects buttons, as well as combine multiple windows on one screen. Axure Pro 9 will require you $29 per month to make a video chat app prototype, and the Axure RP 9 Team will cost $49 each month.

There is no one right choice tool for everyone. Prototyping solutions evolve and change every year, so you should proceed from the proposed functionality and convenience when choosing them.

As soon as prototyping is completed, the moment will come to its practical implementation — His Majesty design.

Design

At the design phase, the issues of visual, tactile, and sound perception are elaborated — from the color scheme to the shapes and distances between the icons.

UI and UX are both sides of the design phase, but still, they are different. So their implementation order matters for the development flow — UX precedes UI.

    

UX is responsible for the intuitiveness, logic, and interconnections in the app’s design. Therefore, before painting the walls, it is worth creating a frame and polishing the mechanics so that only then go to the UI.

When you design and build a video calling app, it is important to think ahead about the intuitiveness of the logic when working with video calls. You need to make the video communication interface elements easily noticeable so that the user can change the microphone/camera settings and write messages right during the video call. Skype is a typical example of a non-intuitive UX, where it’s hard to understand how to interact with the app during video calling.

UI is engaged in the aesthetic fullness of apps. It is especially important for the video calling app development to elaborate the graphics filling of elements on the video panel. Firstly, you need to test a lot of backgrounds when making calls so that, for example, white icons do not merge with a bright light backdrop. Besides, you need to take care of the gradient hover, darkening of the lower block on the player, icons clearness, i.e., everything that will be shown on the video panel.

The three-month symbiosis of UI and UX forms a full-term and healthy product that meets the standards of the time. After the application shell is formed, you need to connect it with the world around — what the backend is directly doing.

Back-End development

When the external UI/UX connections are created, it is time to establish internal ones — the app server, the web server, and the database. This trinity of components is the core of the backend architecture.

Note that the video chat app backend is not primarily about development but about optimization. Since your product has to withstand the enormous loads of thousands of simultaneous video calls, you will need powerful hardware and a lot of effort on performance tuning.

Among the ways to optimize performance, we single out the following:

1. The need to have powerful hardware. With the support of video conferencing, the number of streaming will be squared by the number of users, which will require even greater computing power.

2. Platform selection. There are a plethora of different tech stack components. Their choice directly affects the overall performance of the application, so choose wisely, based on your developer’s experience and video chat specificities.

3. The experienced developers will have a significant impact on backend optimization. They can speed up the development process by code optimization. We recommend including DevOps specialists in the team since they can improve overall performance by dealing with scalability issues.

They will use such foundational performance tuning methods:

• Multi-sampling anti-aliasing (MSAA) to sample every pixel without loss of the frame rate. Technically, it will load the system less, and the human eye won’t notice the changes in video quality.
• Interlacing. This method allows you to remove pixels in real-time on the video. This is achieved by dividing video frames into two fields and layering them on top of each other.
• Compression. This technique helps optimize video data by converting the video file into a compressed file. By eliminating unnecessary file information, the method helps reduce the file size, which leads to less server load.

For video chat app development, the backend architecture must include a signaling server for connecting and exchanging signals between devices, as well as STUN/TURN servers that establish live communication over the network.

Now let’s move on to the choice of toolkits that will be necessary to make a live video chat app.

SDK and API’s that you actually need

WebRTC is the most common and convenient protocol to create a video chat app for several reasons. Its main advantages are browser support and high stability. WebRTC uses 3 APIs, the set of standards, that is responsible for audio and video codecs, P2P connection, and data streaming respectively:

• MediaStream to allow broadcasting from the camera and microphone through a secure UDP protocol;

• RTC PeerConnection to establish direct contact between users and remove the load from the server;

• RTC DataChannel for peer-to-peer communication or data exchange between users.

WebRTC is simplifying video conference app development since it does not require downloading and installing various plugins.

    

There are third-party APIs, which speeds up and simplifies the video chat app development:

• ContusFly;

• Pubnub;

• CometChat;

• Twilio.

At this point, you will have to face a strategic choice: convenience and speed or safety and independence. By creating a solution from scratch, you will get your own data warehouse, in contrast to third-party solutions use, where the proprietary code can have security breaches.

Besides, the problem of dependence on the vendor system exists: having built your project on someone else’s foundation, be prepared that changing it without huge losses and difficulties will not be possible.

Finally, keep in mind that the relatively low cost of developing with service provided API will entail high financial losses in the monthly run as you will have to pay for its use.

Beta version and testing

Quality Assurance (QA) provides product quality control, future problems prevention, and savings of the total project cost. Without this stage, the app release becomes akin to a step towards the abyss without a parachute.

Depending on the app’s functionality, the number of tests may vary during the development process. However, our QA department always maintains a golden mean between the number of tests and output product quality. Also, they achieve the best result and provide an app without bugs by performing an optimal number of manual and automated tests. The main QA tests that are provided for mobile development include:

• smoke testing — all the basic tests, without which it is impossible to switch to more complex ones;

• retesting — bug fixing and various improvements;

• regression test — a large-scale series of the entire program tests after changing the code or functionality;

• performance testing — testing app’s stability and responsiveness during internal operations on the smartphone.

Video chat apps testing has its own peculiarities related directly to broadcasting a high-quality and stable video signal. So that your video chat gives a clear picture and does not spoil the UX, emulate these tests for issues with:

• Bandwidth between the interlocutors, affecting the quality of the picture. To test it, use screen capture or a high-speed camera to record the screens of both interlocutors synchronously.

• The video image quality is affected by technical aspects that spoil the image and are not always captured by the human eye. To test it, use screen capture or a high-speed camera to record the screens of both interlocutors synchronously.

• The general operation of the video chat process is checked for functional interaction during a video call: chatting, muting, reconnect — everything is tested for error-free and stable interaction.

• The size of the occupied space is also worth testing in advance because the video consumes a lot of resources. Keeping the maximum picture quality for any connection, the application should not be occupied with more RAM (Random-access memory) and local memory than necessary.

If your project has strict deadlines and require quick implementation, you can use the following mobile test management systems to speed up the process:

• Jira;

• QA touch;

• Testlink;

• Kobilton;

• Testcomplete.

Be aware that these solutions are payable. Our QA department is ready to work with both free and commercial software and always chooses the best options according to the project conditions.

Make improvements

After the beta version release, the feedback from end-users is collected, on which basis developers are making changes for product improvement. Be it improvements or implementation of entirely new features, regression tests are usually applied, and they account for the lion’s share of testing time.

The A/B test is conducted at this stage, helping in practical ways to determine the audience’s attitude towards your app. This test is employed to create and release two functionally different versions of the product to track user reactions. The most successful version is being refined and released as the final version.

Deployment

Having made and approved the changes after the beta version, the final stage of preparation for the release begins. It consists of deployment on a web server and app stores. Some specific issues can await you on the home stretch of your project implementation, but we will try to minimize them for you by making a list of the most encountered challenges with the web server deployment:

1. Consistency

   To create a video calling app with high-level performance, you need a large number of servers ready to handle the load. When deploying and updating backend versions, their quantity becomes a problem resulting in a noticeable loss of time due to its updating one by one. Therefore, you should update servers one at a time, warningly disconnecting from the general system. The client should redirect to new servers using the Load Balancer.

2. Backward compatibility

   The newer server version must be compatible with the previous APIs version. Therefore, outdated ones are maintained for some period of time, deprecated and deleted.

3. Security

   If you do not want to risk confidentiality and use an out-of-the-box solution, then there will arise a security risk between your servers. To prevent hackers from gaining access to the entire cluster when breaking one server, we recommend you creating the cluster server in one VPN internally. Be prepared to sacrifice 10% of the total performance for the sake of such protection.

4. Key values

   With frequent server reconfiguration, key values may vary. If such a problem arises, solve it by providing environment variables that will change the keywords into values.

Compliance with platform requirements and approval time is what you have to deal with concerning launching your app on the app stores. Remember that the vulnerabilities found in the code may not be closed on time since approval time in the App Store may take up to 2 days. In this case, you will have to add a version check to the server-side and disable the application if the client still uses an older or insecure version.

Adhering to the above steps and successfully releasing your video chat app, you only have to wait for the profit and strengthen the product by timely updates. Now that we know how to build a video chat app in Android and iOS, let’s find out how exactly to make money on a video chat application?

Choose a monetization strategy

An unsuccessful choice of monetization methods can condemn even a well-designed app to failure. We suggest the following monetization methods if you want to make your own video calling app:

Advertising

The most common way to make money in mobile apps is by showing ads. Invasive pop-up ads and built-in ads can appear before watching the video. This method is tremendously popular both for stability and for the opportunity to introduce a paid “Ads-free” mode. As a downside, there is some fatigue from pop-ups among users, which will harm the user experience.

In-app purchasing

For an additional fee, you can offer both cosmetic changes and extra full-value features. In chat applications, premium stickers and filters are especially popular. It is worth noting that this strategy is more than twice successful for iOS than for Android..

Subscription

Even though the subscription will more often push users away, the lack of alternatives on the narrow audience and focus on their needs will be suitable for fulfilling the financial goals. You can get around the limitations by free distribution of the app in the stores and the establishment of limited access when using it.

Sponsorship

Upon reaching a certain level of popularity among users, your application will begin to receive sponsorship offers of an advertising nature for brand promotion. The availability of offers will also depend on your product audience. This method is not suitable for young projects, but it will be a high extra income for more famous apps that synergize with in-app purchases.

    

Now that we’ve figured out how to make a video call app and receive income, let’s focus on the average costs of creating a video chatting app.

Cost of building the video chat app

The price of the video conference app development is derived from the formula of the necessary features and the time required for their implementation. The set of MVP video app features will differ from the full-feature project only in secondary functions and will consist of the functionality appropriate for video calls:

• user registration;

• profile and status;

• search and filter;

• add friends;

• video and voice calls;

• encryption.

If you want to create the most similar product, you will need specialists such as:

• 1 Project Manager;

• 1 Tech Lead;

• 2 iOS developers;

• 2 Android developers;

• 1 Backend developer;

• 1 UX/UI designer;

• 1 QA engineer.

For a full-feature project, you should add at the bare minimum a video conference and push notifications. You may want to include text chat and related features like media file sharing and geolocation, but keep in mind for each extra feature, certain hours will be added, as well as a full front-end part.

Starting with Business Analysis/UX and Technical Specification, which will take from 50 and 20 hours each, you will determine the vision of the project, carefully display its technical features and also think over the UX logic. The UI design will take a minimum of 40 hours since the video chat is a visual-centered product that needs an attractive look. The main stage, iOS/Android development, will require from 400 to 450 hours for MVP. The creation and configuration of the app web server will add another 150-200 hours of total development time. Finally, the QA department will require about 20% of the total time for testing.

Using the above hours, we will show you a rough estimate of the total mobile video chat development average costs:
