It's important to me that the app builder can be mastered very quickly, because if I have to spend a lot of time trying to figure out how to use something, I don't like it very much. I found a cool app builder, which you can also find exactly on this website https://flipabit.dev/download/ . It's very easy to use and it also has so many features I've never seen before in my life. I definitely advise you to try creating apps with this app builder.
