Types & Unique Selling Points of Video Chat Apps

Before we move on to explain how to make a video chat app from both the business and technical points of view, let’s first identify the main solution types.

This can help you understand the differences between options and clarify your intentions for a similar project.

There are three main types of video calling application, including apps for video conferencing, communication, and entertainment.

Let’s discover each video chat app type.

Conference Video Call Apps

Video conference call apps improve collaboration and speed up the process of communication between colleagues, especially when it’s needed to support people in different locations.

These video conferencing services allow users to have around 500 participants at the same time. The main requirement for building this kind of solution is high-quality video and audio calling, and the adjustment based on the speed of the internet connection.

Examples: Zoom, Google Hangouts, Google Duo, Skype, Microsoft Teams, Google Meet

Video Calling Apps

This type of apps for video conferencing allows for face-to-face video calling in everyday life. These solutions for video calling have limited capabilities. In most cases, you cannot use these grouped video calling apps for work; therefore, they are best suited for personal communication.

For example, WhatsApp only allows for four participants, and Facebook limits the number to eight at a time.

Examples: WhatsApp, Facebook Messenger, Viber, Telegram

Video Chat Apps for Entertainment

Video chatting apps can also be used for entertainment or even online dating. You may also check out how to make a dating app that utilizes instant messaging.

A great example is Houseparty, a video calling app serving as a networking service for group video chats between friends. Users receive a notification when their friends are online and available for a group video call.

Examples: Houseparty, Discord

How Does a Video Chat App Work, Technically?

Video calling is very similar to regular phone calls. In addition to hearing the other person’s voice, you can also see them. Many video calling apps also provide some additional services, including video sharing, group video calls, etc.

From a technical point of view, WebRTC is the most popular technology used to build video chat applications.

WebRTC (Real-Time Communication) is an open-source internet protocol that allows users to arrange real-time video calls using simple APIs.

This technology is used to implement a Peer-to-Peer connection without the help of a third-party web server. At the same time, WebRTC can transmit media content.

In a nutshell, WebRTS can be used together with four APIs:

  • MediaStream – this API enables chatting between clients using either a microphone or a video camera.
  • RTCPeerConnection – this API is responsible for the security of video calls, as it enables audio and video data transfer with encryption support and access control.
  • RTCDataChannel – this API provides a Peer-to-Peer communication network for data generalization.
  • OpenTOK – this is actually not an API, but a PaaS platform and an open-source library that can be used to enable cross-platform video chats.

If you want to know more about video call app development like Google Meet, the technology described above powers this solution.

Below, you can see how video calling works with a Peer-to-Peer connection structure:

WebRTC Communication Protocol for Video Conferencing
WebRTC Communication Protocol for Video Conferencing

Here is how the connection between two clients is established:

  1. The first client sends a so-called Offer to another client via a server (PeerConnection Observer).
  2. The second client (Remote Peer) sends a reply to the Offer via the server as well.
  3. The Peer-to-Peer connection is established between the clients.

After the initial exchange of Offers, the server may then allow for further development into a video chatting app, as the data can still be transferred even with the disabled server.

The next involvement of the PeerConnection Observer is required only to properly close the connection, add new members to a group video call, and to perform actions that go beyond information exchange between two clients.

How to Make a Video Chat App: Strategy Development [Steps 1-4]

How to Make a Video Chat App, Step by Step
How to Make a Video Chat App, Step by Step

The process of video calling app development consists of 8 major steps:

  1. Defining the value proposition
  2. Creating a business plan and defining the monetization strategy
  3. Hiring a software development company

Additional Tip: you can define your USP by answering questions: “What?,” “Who?,” “Do what?,” and “How?”

For example:

Google Meet (What?) helps big companies (Who?) conduct big conferences (Do what?) by allowing a big number of participants (How?).

Step 2: Create a Business Plan & Choose a Monetization Model

The next step in the journey to explain how to make a video chat app is to finalize your USP and strategy by employing the Business Model Canvas.

This model covers the following areas and helps businesses to structure all the strategic information, namely:

  • Key activities
  • Key resources
  • Key partners
  • Value proposition (USP)
  • Customer relationships
  • Customer segments
  • Channels
  • Cost structure
  • Revenue streams

Defining the right monetization strategy is no less important than knowing how to make a video calling app from a technical standpoint.

The following video chat app monetization strategies can be used:

  • Advertisements – this model allows you to make your app free for users, as it implies that money will be made from advertisements. You can use different PPC integrations or work with brands directly. By placing ads inside your video calling app, you will be able to make money per click, per ad view, per action, etc.

  • Paid calls – you can make the key features of your app paid services. You can provide users with the ability to make video calls for free for a limited time, allow them to increase the limit on participants for payment, to increase the number of viewers, etc.

  • Freemium – this is the most popular app monetization strategy among businesses. You can provide some basic features for free, and additional features, like blurring or changing the background, adding stickers, sending text messages and files, for a fee.

How to Make a Video Chat App: Functionality & Tech Stack [Steps 5-8]

Now that you know a lot about video call app development from a business point of view, it’s time to decide on some technical aspects.

You need to choose a tech stack that will allow the app to withstand high loads, easily scale, and provide users with the latest solutions.

Let’s examine each of the steps in more detail.

Step 5: Select Video Chat App Functionality

The next step in the video chat app development process is to decide on the functionality of your video calling application.

In the tables below, you can see an overview of possible basic and advanced features.

FeatureShort description

Screen sharingThis is a must-have feature if you want to develop video chat app that will be in high demand. Conference apps for video calling need to support at least 50 participants. For personal communication, the number can vary from 5 to 10 participants.
Virtual backgroundReplacement of the user’s background with a picture is very useful, especially when working from home. By replacing the background, users will be able to hide a mess or anything that they don’t want others to see.
Virtual noise cancellationBackground noise can ruin any conversation. Thus, your app can have a special feature reducing background noise with the help of software.
Custom emojis and stickersAllow users to expand the provided out-of-the-box stickers and emojis with custom options. Users will be able to share jokes and highlight points with stickers and emojis that they seem the most suitable for a situation.
Custom masksThe ability to create custom masks can be great for entertainment video call apps and even conference solutions. Snapchat and Instagram provide a great example of how this functionality can be implemented

Step 6: Create a Customer-Centric UX/UI Design

If you want to know how to build a video chat that users will love, start by creating a user-friendly interface of your solution. You should pursue a minimalistic, intuitive, and attractive design.

There are three main factors that you should consider when designing a video and voice call app:

UX/UI design

This refers to user experience and user interface. Designers usually start with the creation of wireframes (UX) that define how users will interact with your application. As well, it is possible to combine this step with UI design, which allows you to save money and time needed for the development process.


You need to stick to the same design style throughout your video conferencing application. Even if you create a mobile app, a desktop version, and a web solution, it’s vital to ensure design cohesiveness. This way, users won’t have any problems using your application when switching between platforms. Additionally, it will help you create brand recognition and a better brand identity.


As you are exploring how to make a video chat app, one of the most important things is to ensure its responsiveness on all screen sizes. As your app can be used both on a smartphone and on a tablet, it’s important to provide the same smooth user experience across platforms.

For these apps, you need to ensure a secure exchange of data between your servers and devices, as well as the encryption of sent and received data. Additionally, you need to think of good network connectivity and provide the ability to use your video chatting software even with poor connectivity.

Step 8: Test Your Video Chat App

Quality Assurance is a vital part of developing an application that won’t have any issues when it comes to video calling functionality, performance, and security.

Depending on the type and complexity of your project, you might need to perform a number of software testing services, including user acceptance testing, automation testing, load testing, stress testing, etc.

After you launch your application for video conferencing to the market, you will get a lot of real-user feedback.

This data provides the most valuable insight into what your target users are expecting from your application and what their needs are. The insight you receive should be used for further app development and improvement.
