There's an APK, for dabbling on the phone at times when there's no larger computer available but still time to spend.

Having J on the phone in your pocket is great.

And lots of the "labs" (interactive tutorials) are built in too: 3 dots -> Help -> Labs..

Edit: I should also have mentioned that Termux on android can build ngn-k, goal and a bunch of other open source array languages too.

There's also Rob Pike's Ivy language for Android too.

For android and apl we also have dzaima's AndroidIDE which is the best android array implementation that I have found.
