## Description

**Juno** is a zero-setup Python IDE and Jupyter notebook editor for iPhone and iPad. Write and edit Python scripts, notebooks, JSON, XML, and other text files with syntax highlighting, code completion, project support, a REPL, and a customizable notebook editor. Python 3.13 runs locally and offline, with free editing and a trial allowance for executing code.

Pro features include local project execution, scientific packages such as NumPy, pandas, Matplotlib, SciPy, Scikit-learn, and OpenCV, package management, an Object Inspector, built-in web previews, Shortcuts and Siri automation, and background sessions. Juno also offers an AI coding assistant using your own OpenAI, Anthropic, or Gemini API key, plus Python access to native iOS features including location, photos, contacts, notifications, Bluetooth, Keychain, and more. A one-time Pro purchase unlocks continued code execution without a subscription.

## Review summary

Reviewers praise Juno for a tablet-optimized notebook experience on iPad with on-device data-science libraries (NumPy, pandas, Matplotlib) that support runnable code. It’s seen as strong for on-the-go data work, including lab use and Vision Pro. However, pricing is a dominant gripe: essential features require a Pro subscription, and the free tier is largely unusable. Other common complaints include it not being an IDE, awkward file navigation/editing flow, limited package management (no pip), and occasional stability issues.

### Pros

- Tablet-optimized notebook interface on iPad.
- Bundled data-science libraries (NumPy, pandas, Matplotlib) with runnable code on-device.
- Strong option for on-the-go data work (lab use and Vision Pro scenarios).
- Clean, responsive UI with smooth interactions.

### Cons

- Paywall and pricing gating; free tier largely unusable.
- Not an IDE; awkward file navigation and editing flow.
- No pip support / limited package management.
- Occasional stability issues.
