this is totally the opposite of what Thunkable X stands for. The real benefit of Thunkable X against other drag & drop builders is actually that it is two in one platforms. If you seriously think building for only one platform will be a better and going to be a great success then I guess you should reconsider that. Almost every successful app nowadays is both Android & iOS and there are only really few that are really successful and only support one OS… I personally thought a lot about creating apps in Android Studio and x-Code but I really don’t like the idea of having to do all the work twice… That’s why Thunkable X is great.
Also, of course Thunkable X is in very early stages right now and sometimes I wished they would do more fixes than new features but it gets better with every update. Btw. every app builder will always be limited in its features and possibilities… You simply can’t create everything in a drag & drop environment
