2. How to Build A Video Chat App in 10 Steps?

Steps To Build A Video Chat App
  1. Determine the goal and target audience of the app. It will help you decide on your app’s features and functionality. Identify the primary use case like are you building it for personal use (consumers), business users, gamers, or for your own enterprise communication.
  2. Once identified, review the landscape of such video apps that relate best to your use case. This will help you identify the minimum required capabilities and value add for your users.
  3. Hire an in-house team of developers or outsource your video app project to a software development team. Look out for their experience in building solutions in this vertical. Ask for your references and relevant case studies in video streaming and communication space.
  4. Pick a programming language and framework. Many choices are available, including React Native, Java, Kotlin, and Swift if it’s for mobile apps, React, angular, or Vue for web apps.
  5. Create a video chat app prototype. By prototyping its design and interactions, you can evaluate a video chat software’s future appearance, interface structure, and usefulness.
  6. To implement the user interface, design and build screens and views for user interaction, such as login, main chat, and settings screens. For a wider audience, use an intuitive and minimalistic design and ensure technical proficiency for users of all ages.
  7. Create the backend of the video chat app. There are several options for creating it. One option is to build it from scratch, which provides greater flexibility, or to use the communication platform as a service (CPaaS) to save time.

Different protocols like WebRTC, RTSP, and HLS are available. Let your product development team pick the right one according to the app’s requirements and the devices.
  9. Test and debug the app. It will involve testing the app on various devices and fixing any issues.
  10. Publish the mobile app to the app store. It will involve submitting the mobile app to the appropriate app store (e.g., Google Play Store or Apple App Store) and following the submission guidelines.
  11. End-users play a crucial role in developing and building a video call app. They provide valuable resources for the development team in providing feedback and input.
