Very useful platform for developing a large range of applications as well as GUI. Whether is is for IOS, Android or Desktop, it is very useful. I used it while developing python GUI for desktop and it was perfect

The only problem that I have encountered was that is seems difficult to use. It was not easy for me to get out of it.

Overall experience with Qt is superb as it reduces our software development cost enormously. Cause using Qt allow us to write the code once and then compile it for all the operating system instead of developing code for each platform separately.

The best thing is that you can develop and build software for any operating system using the Qt framework as it supports Windows, Mac, and Lunix. Moreover, it also supports mobile app development for IOS and Android. So this is an all-rounded software development framework and environment that build the same software program on for any operating system. Furthermore, the guide and easy to use development environment make this software best to develop any software.

Currently, I use Felgo plugin to develop a mobile app using Qt environment and If Qt improves its native framework up to Felgo level so that will be great to use native framework instead of using Felgo plugin.

getting accustomed to it is easy and can find examples of how to use certain widgets as it is popular

Qt has a complex end user license is better to purchase its full version
