Questions, bugs, or feature requests are welcome at songhuiz442991@gmail.com
To help us investigate, please include your iOS version, iPhone model, app version (found under Me → About), and the steps to reproduce the problem.
Frequently asked questions
Does it need an internet connection?
No. The Python interpreter and libraries such as numpy, pandas, and matplotlib are bundled inside the app. Once installed, you can write and run code entirely offline.
Can I install packages with pip?
You can install pure-Python packages (requests, rich, and similar) by running pip install <package> in the terminal. That step requires a network connection.
Packages with C extensions cannot be installed. iOS does not permit an app to compile or load new binary code at runtime — a platform-level restriction that no Python app on iOS can work around. This is exactly why numpy, pandas, and matplotlib come pre-compiled and bundled.
How do I import existing code?
Open the Files tab, tap + in the top-right corner, and choose Import Files or Import Folder. You can pick content from anywhere in the iOS Files app, including iCloud Drive and other cloud providers. Items are copied into the app; the originals are left alone.
How do I get my code onto a computer?
In the iOS Files app, go to On My iPhone and open the Pycket folder. From there you can copy files to iCloud Drive, send them via AirDrop, or transfer them over a cable.
Is landscape supported?
Yes. Rotate your device and the layout adapts. Landscape is noticeably more comfortable for longer code.
Will deleting the app erase my code?
Yes. iOS deletes an app's sandbox along with the app. Export anything important through the Files app before uninstalling.
Why won't a particular Python library run?
Some libraries depend on capabilities iOS does not provide — multiprocessing, spawning subprocesses, GUI windows, or runtime compilation. These are platform limitations. matplotlib is configured for image output and plots correctly.
Is my code ever uploaded?
No. The app collects no data and your files stay on your device. See the privacy policy for details.
