## What is Pyodios?

Run Python on your iPhone or iPad, with nothing sent to a server.

Pyodios gives you a nearly real Python workspace: Jupyter notebooks, a script editor, an interactive REPL, plots, package management, and a variable inspector, all running on-device. NumPy and matplotlib come pre-loaded. Install pandas, scikit-learn, Plotly, and hundreds of other WebAssembly compliant packages from PyPI with a tap.

Feature highlights:

- Jupyter-compatible .ipynb notebooks with code and markdown cells
- Python script editor with syntax highlighting, folding, and snippets
- REPL with history, search, and code completion
- Static matplotlib plots and interactive Plotly, Bokeh, and Altair charts
- Environment panel with DataFrame viewer, variable diff, and watch list
- Offline Help view with search
- Files browser with iCloud Drive sync
- Package installer powered by micropip with offline wheel caching
- Remote Jupyter kernel support (token, password, or SSH tunnel) [experimental]
- Nine built-in color themes plus a theme editor
- iPad multi-pane workspace

Your code, notebooks, variables, and plots stay on your device. No account. No sign-in. No telemetry on your work. Works offline once Pyodide has initialized and packages are downloaded.

### 1/5 — Stuck in app launch

*2026-06-24*

This app doesn't get past the startup page. It stays stuck downloading a (13MB) file, and never goes past that.
Would give another rating after the dev fixes this.

**Developer response:** So, it does... If you're on an older iPhone/iPad not running on iOS 26 as noted on our documentation/support site, you'll unfortunately run into problems when we're loading in Pyodide. The next version that's coming along shortly bumps the requirements to iOS 26 and above. In addition, it provides a warning on iOS devices with 4 GB or less RAM including a note to close background applications.
