2. Video Calling Apps

If you are living oceans away from your family, then video calling apps are your lifesavers. These apps support uninterrupted calling with great video/audio quality (provided that you have consistent internet connectivity).

Though these apps are cherished when it comes to making overseas calls, you cannot use these apps for work calls and online conferences. There are certain restrictions on video calling apps like Whatsapp allows you to add only 4 members in a group call while facebook limits this number to 8 members.

Examples: Facebook Messenger, Whatsapp, Viber, and Telegram.

3. Video Chat Apps for Entertainment

When it comes to entertainment we first like to involve our friends with us. Video chat apps like Houseparty have no doubt enhanced our bond with our relatives and friends even during the lockdown. These apps tell us when our friends are online and available for video chats. Moreover, these apps offer amazing video filters that you can use while talking with your friends.

Remember the times when you with your friends synchronized the timing to come online together and chat?

Examples: Houseparty, Instagram, and Discord.

Working Model of A Video Chat App – Technical Upfront

Just like a simple phone call, the line gets connected to the other person, and apart from listening to the voice of that person you get to see them on your devices. Prior to the pandemic, video chat apps were basically used to call people living in faraway countries.

But COVID-19 changed the trend and people living in the other house lane or merely in two house distance started using video chat apps to call each other. Anyways, these apps have more to offer us than simple video calling, they give us the benefit of video sharing and creating personalized groups as well.

Speaking technically, most of the video chat/calling/conferencing apps use WebRTC technology. This technology is an open-source protocol that allows the users to make real-time video calls using APIs.

WebRTC establishes a peer-to-peer connection without renting any help from the third-party server simultaneously supporting the transfer of media content.

Video Chat App

WebRTC can be integrated with 4 APIs:

Media StreamAPI for voice calls using a microphone or video camera.
RTC PeerConnectionAPI for secure video calls. Supports end-to-end encryption and access control. 
RTCDataChannelAPI to establish a peer-to-peer connection for arbitrary data transfer.
OpenTOKnot an API but a PaaS service that has an in-built library for cross-platform video chats.
