This is fantastic!

Finally, a Java compiler that doesn’t run in the cloud! Take my $20, you totally deserve it. iSH doesn’t even have enough memory for the JVM.

Sehr gute IDE

Sehr gute IDE, es fehlt mir leider nur die Möglichkeit die Vorschläge direkt unter dem Cursor zu sehen wie bei Intellij bspw. und diese per Tastendruck an einer externen Tastatur (Magic Keyboard) zu bestätigen. Sonst Top!

Documentation is poor

I cannot figure out how to specify a command line argument. Searching the word “argument “ in the documentation yields nothing.

Code keeps deleting itself

I'm not sure if this is an actual issue with the app or something I'm doing, I don't know. Every time I tried using the free version of the app on my iPad, I suspended the app for a few minutes to mess with some other apps (without completely closing CodeBrew), and each time I came back to CodeBrew my entire code was deleted. The only thing that remained was the name of my Java Class and the default starter main code of "Hello World". I put 3 starts just cause I never really got to test this app out because of that issue, but yea, I don't understand why that is an issue.
