Cloudy

This isn’t a JVM or a JDK you run on your iPad or iPhone; it’s a shell that sends files off to the cloud to be compiled and run. You have to pay for that, $0.99 for 100 compilations, or $2.99 for unlimited.

It doesn’t seem to really have files; I created a file, typed a small java program into it, saved it, and then went to the files application to find it, and it wasn’t found on my iPad.

I’ll be deleting the app soon, My hunt for an IDE for the iPad continues.

Slow to compile, Slow to run, Cash grab

Tried to switch to this after my old app was taken down. Major downgrade

Terrible

It’s a free app but to make it work you need to pay!!! 🤬 This is absolute rubbish. Don’t get it if you’re after a free coding app! 😡

Deceptively Free

I will admit that I fell for the “Bait and switch.” You need to pay $3 to compile more than one program after installing the app.

Refund

I just bought a $1.49 (100 compilations) and a $4.49 (Unlimited compilations) and it can't even run my Sum.java program. I would like a refund please.

Nice compiler but one issue...

I really like this app. It’s nice being able to edit a java programs on the go. However, my issue is that there is no way to actually use a scanner to input into the console. Take this into consideration before downloading!

Broken Tab bar

The tab bar does not load at all after purchasing the in app purchase. I cant switch between input output and other tabs because it just a black bar now.

Love it

I’m brushing up on my java for the first time in a year. Normally I’m on the computer but I’ve been more on the go and it’s perfect! Love the app, sometimes it’s a bit slow but other then that lovely. If you do or like java this is a great app to use!

Greedy

Doesn’t let you run unless you pay. Don’t male it free if you can’t even partially use it.

Not worth even half star 👎

DO NOT WASTE YOUR TIME AND DATA, Complete rubbish App.

Response from developer

Please provide more details in your review.

Good app

Can be better, but it work and it's perfect for to do simple files.

Only Text?

Original Posting April 2013:

Purchased app. Programmed with java.io.* class. Works fine. Next attempted a simple Hello world with javax.swing.* Well it compiles but gives a "The program raises a runtime error" error when executed. Seems any graphics at all are out of the question. Sure would like to know prior to purchasing what java classes are supported...

April 15, 2017:

To respond to the developer, there is no input for hello the hello world swing output. As I indicated above it would have been nice to know that the app only will work with non-graphic programs otherwise you get:

Exception in thread "main" java.awt.HeadlessException:
No X11 DISPLAY variable was set, but this program performed an operation which requires it.
at java.awt.GraphicsEnvironment.checkHeadless(GraphicsEnvironment.java:204)

Response from developer

Please check if you entered text input on the Input screen before running the program.

Terrible

Would not recommend

Update: My problem is that you have to pay just to compile it. What's the point of it then?

Response from developer

Please explain your problem, so we could make our application even better!

Can't compile without paying for it lol

You have to buy something that's free on any other pc, that takes the integrity directly out of the app. I would've respected if the dev put a price on the app itself, but this is useless. Very unfortunate.

Wonderful and intuitive

Love using it when not close to a desktop.

Money-waster

This junk is not free, you need to pay to run any code you type. If you want to use java, this app isn't for you, just go on a laptop or desktop, and use eclipse or something.

Response from developer

But also you can just buy it and use as much as you want!

Atrocious

I cannot believe they will charge you for compilations. Complete d*** move. Do not install this

Response from developer

You can buy unlimited compilations package and never pay again!

Horrible app

Looks cool however you have to pay for compilations of code which is practically useless. May as well make the app cost money opposed to giving it out for free then having people buy compilations

Response from developer

You can buy unlimited compilations and never pay again to compile your program!

Stupid App

You certainly sould not hace to pay for compiling in a compile essential language I reccommend buying a better app or using Netbeans on PC

Response from developer

Unfortunately, we can't offer free compilations with the application.

Good but

You have to compile every time you want to run a program. This is annoying especially since you have to pay for compiles.
