Good Potential, but still missing adding java files
Re-downloaded it and bought the 2.99 pro version. You can make things from scratch -which is a good for practice. But there is a missing feature to add and remove files, to transfer files to computer.

Nice for some experimental coding
Very nice app for experimenting and exploring ideas while away from the PC; very useful for when I am waiting in line somewhere, and an idea pops into my head. The free version is just to give you an idea of how it works, and the price if the pro version is good considering what one can do with this app. Highly recommended!

Decent for the only real Java compiler out there
So this compiler seems to be the only real one out there for the iPad. However, it doesn't have the ability to change file or project names, it doesn't allow undo, its tab space is 2 spaces, and its font is not monospace. Ultimately, I'm using it because I need to learn Java and don't have a functioning computer, but still, it would be nice if they would add more basic features.

Free version is useless
Simple interface and very functional. I used to recommend this to my students as an on-the-go compiler. Supports imports and Scanner inputs. Wouldn’t mind a scaled-down app without imports or something in the free version but as it stands, files can’t be edited at all. It’s just a proof of concept for “hello world” to sell you on the Pro Version. Would happily pay for a “Pro” version if I could still recommend the free version to my young coders.

Works but I can't see variable names
I wrote a simple program with for loop printing numbers but I couldn’t see the loop index. I’ll try to repeat it here: for (int thisIsMyForLoopsForLoopIndexVariableButWithShortVariableName_HeyThisIsJavaAfterall; See, I had to give up at first semicolon due to screen being too narrow for even the shortest of Java variant names.

Not try? Then no buy.
Even at 2 bucks that’s the fee for a bus ride home. Sorry if you are going to advertise this demo at least give some functionality to test the many interfaces someone can make before buying. Not worth it to be on the iOS market. From developer to developers . CHANGE THIS NOW! Maybe you wouldn’t get 1 star from new potential buyers. Something to think about. You will always lose money when opening a business⚠️😉

Incredible
Best programming app for Java that is out on the App Store. If you’re a programming student, its worth the $2.99 for the Pro 9 version. Does everything a regular desktop program does!

Forces to buy pro
The one thing I hate about this compiler is that it forces you to buy a $2 pro version to edit, the one thing they could do is add a free demo. Or just add a free version with less abilities than the pro version, Everything else seem to works well.

Could be great but needs some work.
Right now this is the only decent Java ide on iOS but this is definitely not perfect. Here are some of the features I would like added: Better text highlighting. A autocomplete system. <- What I want the most. Classes to be broken between separate Java files and tabs to quickly switch between Java files.

Pointless
There’s is absolutely no point in this app because to modify it you require to pro version, which costs $2.99.

Free version is useless. Can’t edit, only run “Hello World!”. Dev should at least enable some coding to entice users to purchase the pro version.

Good App overall, but could use some improvements
Overall, this is the best compiler for java that I have found on the App Store. However, a few problems that I have found with it are the inability to delete what one has just typed in when using a scanner. This leads to issues when testing functionality of a program. Another issue I have it the ability to not be able to make two or more java files, and then save them. It would be really helpful to be able to have the ability to store and save multiple files. Other then that, I really like this app and would happily change my rating to 5/5 stars.

Program Java on your iPhone!
This app is just awesome! Finally I'm able to create a quick "foo" Java app on the go w/o ever needed to boot up my laptop. You can even create file directories and save your Java files in the app for later use. The app even provides compilation errors. Best Java app I've ever used on a mobile device! I recommend downloading the DevKey keyboard too if you don't have a Bluetooth keyboard because it will save you a lot of headache when trying to input scripts from your iPhone or iPad. This keyboard provides quick shortcuts to all the commonly used programming formatting characters like parents and braces.

Fully accessible for blind developers
I just came across this app and downloaded it out of curiosity. In my few minutes of initially playing around with it, I found that it worked perfectly with VoiceOver on iOS, the native screen reader used by blind people to access their iPhones. As a legally blind technology enthusiast myself, I just want to offer kudos to the creator Pico and say thank you for making your app accessible to those with visual disabilities. I will definitely be telling friends and colleagues about this great learning tool. of

Greatest compiler on the market
I downloaded this app a few weeks ago, and have been testing it. It is the only good compiler on the App Store, and as far as I know, it is the only offline Java compiler. With that in mind, I do have a few critiques. I am unable to copy and paste in this app, and I see no logical reason why I shouldn't be able to, unless it's a pro feature. However, I looked at the pro version and I did not see anything in the description about cutting and pasting. Another feature I suggest adding is allowing users to rename the class. And to be able to move classes between folders. If the cut and paste issue gets fixed, this app would automatically get a 5 star review. And if the other features were added, I would consider buying the pro version just to support the developer, because I've been looking for an app like this for years.

It's a keyboard trap! ... Unless you press Output!
Can't escape output screen. Keyboard won't hide. Good grief. Unusable app. Wasted money on pro. Update: Developer responded kindly about how to get around the output screen issue by tapping on the title Output. Definitely not obvious as the normal Apple style Back/Return link has a trash can there in that spot, so didn't know the title bar did anything. Recommend better layout/clarification, but at least this is useable now. Thanks.

So so so much potential
The built-in Math class makes this app perfect for small programming challenges, like codecademy or Euler problems. Really comes in handy when I'm thinking about a problem on the bus or have a revelation on the road. I only wish there were some more built-in classes, but after emailing the developer, sounds like an update is coming soon.

Great! Just one thing...
I love this app, as it lets me edit offline and works very well! That said, when I use a scanner input and run it, I can't put the keyboard back down or leave the output screen. I then have to exit the app to get back to the script. Otherwise great app and I love the new font size feature!

Needs some work
The app is great overall, however, there are a few things that need to be fixed. 1. When using a Scanner or BufferedReader, you can't delete anything you type 2. After using a Scanner or BufferedReader, you can't get rid of the keyboard to go back to your project. 3. When you return to the next line, your cursor jumps to the line below the new line. The only work around for the 2nd issue is to tap on the globe icon (to switch keyboards) and quickly tap where the menu bar is under the keyboard, however, this is very inconsistent. All in all, it is a great app and I would definitely recommend it.

Great app
This is a good app I have no issues with it. I'm able to create my own projects, move quickly between screens, and write complex codes. My only issue with the app is that on the output page it is impossible to erase or backspace which can get quite annoying on an iPhone where an accidental mistype can ruin the whole project.

Amazingly Quick Java Compiler, Easy To Use
Been using this app for a couple of weeks, got to say I'm impressed. It's quite easy to use and it's pretty fast. The one thing I would suggest is that you add an option for JOption's so we can have windows. But other than that it's really good!
