But the video calling apps demand more complex technologies. Hence, the best decision would be to build your in-house server from the ground up.

The main difference between iOS and Android platforms is that different programming languages and SDKs are required. It’s also possible to create an app for both of them using a single code base by means of cross-platform development frameworks like React Native or Flutter.  

Software testing. The common misconception is that once the development stage has initially completed then the app is ready. Thus, the testing stage is considered as an additional and not obligatory step. In fact, if you neglect the testing stage, your app is sure to have full of bugs making it unusable. Thus, a normal amount of time spent on software testing in the whole development process is about 25%.
