So we should circlejerk over this just because he's 17? I know a lot more good developers that are even younger [1]. He should be getting as much critisicism as anyone else. You
need criticism to get better.
Now for the criticism....
I sometimes use the iPad as a development environment, and this is approaching it in the complete wrong way. If you even want to think about developing on-device, then you have to jailbreak. That isn't even like, a question. Then all you need to do is get theos [2]. You don't even need a mac build server. The iPad compiles the code. And you can run it without a developer's license.
It's basically $100 license + internet connection + an mac server to build on + ths app's price vs. completely 100% free (+ your choice of development environment instead of being locked into a proprietary GUI text editor). That's why this isn't good.
