Pythona - Python 3 IDE

Run Python — and large language models, fully on-device — right on your iPhone and iPad. Pythona is a full-featured Python 3.14 IDE that brings real scientific computing, notebooks, and local AI to your device.

Jupyter-style notebooks Write and run Python in cells, just like Jupyter — charts, tables, images, and math render inline. Open, edit, and save .ipynb files to run data analysis and experiments anywhere.

On-device AI & machine learning Run large language models entirely on-device with MLX, Apple's ML framework for Apple Silicon — inference runs locally, no API keys required. Try the included local LLM demo to get started in seconds.

Scientific computing, preinstalled NumPy, SciPy, scikit-learn, Pandas, Matplotlib, OpenCV and more come precompiled and ready to import.

A local Python environment

• Python 3.14 with popular libraries
• Smart, fast code completion
• Syntax highlighting for many languages (JavaScript, C, Rust, Go, HTML, CSS, Shell, and more)
• Markdown file preview
• Create, save, and organize your scripts, and install more pure-Python packages via the built-in package manager

Whether you're prototyping ML ideas, running data analysis, or learning Python on the go, Pythona puts a genuinely capable Python environment in your pocket.
