There can be an app for everyday users who simply want to communicate with their loved ones; they can be friends or families. On the other hand, we can create a video calling application for companies or enterprises who need to conduct frequent meetings with clients or among employees.

Keep the target audience in your mind, and make sure to build a video calling application that satisfies your target audience’s needs. Because in the end, your target audience is what matters.

Let’s discover the several types of video calling applications.

Video Conferencing App

Users generally use such kinds of video calling apps for professional purposes. Video conferencing app involves collaborating with many users (almost 500) to speed up the entire communication process and fill the remote working or distant learning gap. Generally, these apps even allow users to participate from different locations.

The basic idea of video conferencing apps is to support numerous users in one single call and from different locations. The foremost requirement for building a video conferencing app is high-quality (HD) videos and audios. Along with it, the quality of the video should adjust with the internet speed of users.

A famous example that is leading the game in video conferencing apps is Zoom. Zoom was launched in the year 2013 but rose to fame in the year 2020. It supports 500 participants in the conference call. The monetization policy it follows is allowing 40 minutes of uninterrupted conferencing. Still, if the enterprise/organization wants to bypass the 40-minute time, a subscription must be purchased. Screen sharing, encryption, and live chats are some of its prominent features. Zoom even permits users to change their backgrounds and adopt virtual backgrounds provided by them. When it comes to the view, Zoom authorizes 49 open windows on a single screen.

Another well-known example is Skype. It is a video chat app and rather an app for messaging. The video conferencing feature of Skype grants up to 25 users at one time. It has free voice/video calling options and lets users share multimedia and texts. One of the first video calling players, Skype is a Microsoft product leading the app industry game.

Thus, if you want to dive into the video calling app industry, your video calling app concept should be strong with unique features.

Pro Tip: Incorporate elements that allow more than 500 participants at a time.

Video Calling Apps

Some apps are majorly developed with messaging/chatting features but also beholds video calling features. Regardless, these apps are especially for messaging, but still, they have features that support video-calling. Whatsapp messenger or Signal app can be considered as examples of video-calling app. This app doesn’t allow many users to connect at one time, but instead, a group of 4-8 users or a one-to-one video call can be carried out by it.

These apps basically help in personal communication with family members, groups of friends. As apps like this can not support many participants, they are not meant to be used for professional commitments which need conferencing with more participants. But they’re good enough to keep in touch with close groups.

Entertainment Video Call/Chat Apps

Video chatting apps that also host entertainment features are witnessing quite a rise in the digital era. The entertainment video call/chat apps allow users to chat/call and even play games or do entertaining kinds of stuff together from a distance.

Houseparty or Discord, or Snapchat can be examples of entertainment video call/chat applications. Houseparty is a multi-user platform; it is mainly for a group of friends who can interact with each other on the app. Whenever one of the users/friends comes online, the other users receive a notification or even send invites to join the group party. The app also hosts games for the group of friends to play together while chatting or calling.

Features of Video Calling Applications

The next move in the video chat app development process is to decide on the features to include in your video calling application.

We have segregated the features based on the basic features and the advanced features:

Basic Features of Video Calling Applications

Simple Registration 

Registration should be pleasant rather than filled with do-to lists. It should be simple and convenient for users to accomplish the main task: having a video call. Let users add their names before entering the call for an easy-peasy registration process.  The other way round for registration is to let users signup with their email id or social networks; this should be a short manual process. Engaging user experience for registration is a must.

Profile Management

Profile management, as we see, is one of the features of video calling apps. To enable end-users to interact with other end-users, profile management is a must. Through profile management, a user could easily manage its personal details such as emails, phone numbers, direct profile, passwords, etc. For paid apps, profile management should contain a detailed section of payment details.

Contact List

For a more engaging experience, integrating the phonebook with the app will allow users to call the other user from the app directly. However, asking permission from the user to ‘sync contacts’ is a must. The ‘contact list’ feature should directly pull out contacts from the phonebook.

Video Calling/Voice Calling

What is the prime thing we are focusing on? Yes, video & voice calling. Both voice & video calling features in the video chat app should be included. Accordingly, comprising the voice call element in your video call app will help users who are distant from each other to remain in contact. Foreign calls are expenses so that the in-built calling feature will be light on the user's budget on both sides. Taking care of real-time connection, quality of audio & video is necessary for the application. End-to-End Encryption There are already many apps discarded by users due to a lack of security in that app. It would work wonders for you to offer an end-to-end encryption security system and help your app in the long run. End-to-end encryption gives users a sense of security while using the app, integrating this feature will up the chances of your app being downloaded. Adopt protocols that support end-to-encryption.


Geolocation - geolocation is a prominent feature to add if you are planning an entertainment app. With geolocation, users would be able to find users near them and interact with them easily.

Push notifications

Push notifications - with push notifications, the app can effortlessly notify users about upcoming events, calls, messages to join in. Even missed calls or any updates can quickly be notified to users with integrating push notifications. Mobile app development companies consider push notifications a powerful tactic to engage users in using the app in minimum effort.

Advanced features of video calling applications

Screen sharing

Screen sharing has become a must-have feature in every video calling application. Integrating the same will allow users to share information present on the screen with other users who are on the call. More importantly, this feature has become a prominent one for better collaborations of projects & tasks among multi-users.

Virtual Background

Working from home has become the norm. In that scenario, picture backgrounds that can replace the original environments can make users go gaga over them. Virtual backgrounds should allow users to change their original background to something innovative. For example, a user who wants to sit in front of the Eiffel tower should easily change the virtual background.

Virtual Noise Cancellation

Background noise can ruin conversations, but integrating virtual noise cancellation can come as a saviour to many of your users. Thus, your app can have virtual noise cancellation software.

Cost to make a video chat application

Now that we have covered the features, let’s move to an essential point.

  • The technology stack
  • The features you want to include
  • Platforms you choose (iOS, Android, or both)
  • Software development company you choose
  • Analyzing your business
  • The app designing (themes, colours, graphics, visuals),

Developing a video chat app starts at $40 per hour. The estimation is mainly based on the features to include and the development time it would take. If the app development process goes for 3-6 months, then the estimated charge would be $40,000-$60,000, and if it is for 9 months, then the cost can rise up to $1,00,000 -$1,25,000.

Please take into consideration that the above figures are just estimates.
