### 5/5 — This is fantastic!

*2025-12-08, version 1.1.1*

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.

### 5/5 — Sehr gute IDE

*2025-11-11, version 1.1.1*

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!

### 5/5 — App zum üben

*2025-09-25, version 1.1.1*

Gute App zum üben von Java wenn man unterwegs ist.

### 3/5 — Documentation is poor

*2025-09-04*

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

### 3/5 — Code keeps deleting itself

*2025-08-25, version 1.1.1*

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.

### 2/5 — Limited runs per month?

*2025-05-27, version 1.1.0*

Why? I mean, it’s a good app, I guess, but this just turns me and probably a lot of people away.

### 3/5 — The amount of runs you have if don’t do the pro thing

*2024-12-11, version 1.0.2*

Stop this pro thing because it’s really a problem. Not even VSCode does this

### 5/5 — Very convenient!

*2024-12-04, version 1.0.2*

I’m learning Java and this app is useful for doing small coding projects or just playing around with Java code. I haven’t done anything “large scale” on it yet to test it’s limits, but it’s been able to run everything I put in it. 

The format feature is super useful and I like the syntax error checking system. I also enjoy the fact that you don’t need Wi-Fi to code in the IDE. 

The only problem I’ve had so far is the hints/autofill come and go and I haven’t been able to figure out why. It could just be me though. 

Thank you for making an app like this!

### 4/5 — Хорошо

*2024-11-25, version 1.0.2*

Отличное приложение но к сожалению при попытки зайти в настройки приложение вылетает:( (iPhone 5se)

Из плюсов красивый и удобный интерфейс, есть подсказки кода

Из минусов только цена наверное

### 4/5 — Отлично, но...

*2024-05-28, version 1.0.2*

бесплатная версия ограничена количеством запуска кода, а про версия слишком дорогая :( так что придется искать другой компилятор было бы славно, если бы подарили ее :)
