Did you try my retro programming app for iOS already? If not, this is a good moment! With the new version 4.0 you can play all games from the community for free now. As before the free version also allows you to write your own programs with up to 24 lines. The upgrade to the full version is only required, if you want to create more complex programs.
I thought about this concept before. It seemed unfair that programmers, who are an important part for the success of this app, should pay for it, but players not. So I asked active users of the community about it. The answer was that they didn’t mind to pay for LowRes Coder, but they would like to have a larger audience for their programs. So this is what I try now.
