These businesses are keen to undertake video conferencing app development. So let us find out how to develop an app like Zoom.

Choose a Development or Application Platform

Even before the actual app development process starts, a business has to decide on the type of platform on which you wish to run the application. It helps in deciding the cost structure and required development tools, a time frame of the completion of the app, etc. Here, you have to ask yourself one important question, that is :

Do you want the application to run on laptops, smartphones, desktops or tablets? You can choose all these platforms and develop accordingly or you can choose one platform to host the application. You can decide the platform depending upon your objectives, business goals, target customer base, available budget, etc.

Native Apps

If you decide to go the native way, you can select the platform on which you can deploy the application. Usually, Android and iOS are backed by their own, distinct programming languages, Java and Swift/Objective-C, respectively. So the developer will have to develop a separate mobile app development for both iOS and Android platforms. The developers can also use a programming framework like React Native which can help in building apps that can run on Android and iOS devices, both.

Web-Based Apps

Developers usually think of building this kind of application first. These apps can be accessed through any device. Plus, there is no need to use an extra third-party tool. Use of programming languages like JS, HTML is possible. Building the video conferencing app is easier using web-based apps. If you wish to make your app that can rock both computers and laptop markets this is perfect.

On the other hand, if you wish to provide more scalability to your app and more power to run effectively on the respected platforms, native apps make more sense. These apps also support legacy devices.

Progressive Web App

Video concerning will be an incomplete experience for the users if they do not have any other way of communication attached to it. Hence, chat. Integrated can't feature will allow participants to talk to each other individually or to the group at once. Can't during the call is crucial for better communication.

Pre-Call Video Preview

Let the application users check the camera before they host or participate in the video call. Let them have an option of deciding whether to enable or disable the video if they wish so.


Activities like conducting presentations or virtual background meetings or conferences usually require the host to share important files with others. The exchange of media files or online documents during the meeting or video adds to the convenience. All these exchanges and sharing of data must take place in a secure environment.

Multi-party Conference

Any video calling app like Zoom can be successful only if it can support more than two participants. A multi-party conference feature Developing such apps takes time and effort, but this feature has to be there as it is the heart and soul of the application.
