Run Ruby on Android — On-Device and Offline
Run real Ruby on your Android phone: a genuine interpreter, bundled in the app, executing on-device with no connection. What runs, what it's for, and the honest limits.
Ruby is a joy to write and, until now, awkward to run on a phone. PocketCode fixes
that by bundling a real Ruby interpreter inside the app and running your .rb
files on the device — offline, with nothing to install.
Real Ruby, running locally
This is a genuine Ruby interpreter, not a lookalike. Open a .rb file, tap
Run, and Ruby executes on your device:
- The expressive core you actually use — blocks, iterators,
puts, string methods, ranges, hashes, symbols — behaves as Ruby should. - Output and errors stream into a proper console.
- It runs with no connection, and nothing leaves the device.
What it's great for
- Learning and practicing Ruby — follow a tutorial, drill exercises, test an idea on the spot.
- Scripting — quick text processing, data munging, small automations.
- Prototyping logic — sketch a method or a small class and run it immediately.
Around it you get the editor's autocomplete, navigation and on-device formatting, plus a programming symbol bar so Ruby's punctuation isn't a fight with the phone keyboard.
The honest limits
- Standard-library Ruby, run locally. It's for running your own scripts, not a gem-install workflow — think Ruby without a package round-trip.
- Interpreter speed on a phone. Great for scripts and exercises; heavy compute will trail a desktop.
- Not a Rails server. It runs the language for scripting and learning, not a full web-app stack.
Within those lines, it's real Ruby, in your pocket.
One of many
Ruby is one of five languages bundled and ready offline the moment you install — alongside Python, JavaScript, C and PHP — with a dozen more as optional packs. See the full lineup.
Your phone runs real Ruby — offline, private, instant.
