J programming language

By Jsoftware Inc

This app is only available on the App Store for iOS devices.


J is a general purpose, high-level programming language. J is particularly strong in the mathematical, statistical, and logical analysis of data and visualization of your data is at your fingertips.

If you are new to J and want to be a J programmer, this is a good place to start. If you already know J, you probably think of it as fun rather than work. Now you can have mobile joy of J!

Customer Reviews

This is awesome

I rarely care enough to write a review, but this is excellent. Having J in my pocket was what I needed to finally learn J, having tried a few times over a couple of decades. Not just that, the UI is very good.

Edit: if this isn't updated, it will cease to work come iOS 11 :(

So convenient

Can't find a J compiler ANYWHERE online.
This app does what it says very well.

The one nicety would be if it were optimized for iPhone 6+ screen sizes, as the app is currently iPhone 4-sized.

Great app, but could be better

I love J, and it's fantastic that I can now use it on my phone. However, the input device hangs when trying to write an explicit verb, such as '4 : 0'. Also, this app could benefit from a custom input device--regular phone keyboards just aren't made for programming.
