WORKS COMPLETELY OFFLINE
Everything runs on your device. Write programs, manage your files, use the REPL, run numpy/pandas/matplotlib, and switch between notebook and script mode — all without an internet connection. No cloud. No account. Just open the app and start coding.

PRO — MONTHLY OR ONE-TIME LIFETIME
Upgrade to Pro to remove ads and unlock the full library set, including beautifulsoup4, pillow, openpyxl, seaborn, plotly, fastapi, httpx and pytest. Two ways to pay: a monthly subscription, or a single one-time purchase that is yours for good. The monthly plan renews until you cancel, and you can cancel any time in Google Play.

Ratings and reviews

This app is a one of, if not the best python app(s) that could run on a phone. It's free version delivers when I use it. I would definitely recommend it to anyone looking for a python editor.

great app with great potential!👍👍,,,but limited to 10 'RUN' command limit perday! even the very basic functionality is behind pay wall! very poor presentation! most apps like this offer some libraries, customisation features,AI features, server access etc as premium features... but here the basic functionality...ie... running a snippet itself is limited upto 10 times.... making the app practically useless..... uninstalling it because there are some practical apps still exists in play store..

bro did you think you were smart making the input()s appear on this little bar at the bottom and not like an actual terminal. apple

What’s new

Fixed: no ad-consent screen in front of a new install. The app opens straight into the editor, and if your region requires a consent choice it is asked later — never before you have used the app. You can change or withdraw that choice any time in Settings > Ad Privacy Choices.
