Our verdict on Juno

Juno is a native Python development environment for iPhone and iPad, aimed at developers, students, analysts, and notebook users who want to write and run Python without leaving an iOS device. It combines Python files, Jupyter notebooks, multi-file project workspaces, and interactive REPL sessions in one app. A local Python 3.13 interpreter supports execution, while code completion, an Object Inspector, scientific and data-analysis libraries, and rich output viewing extend the editing environment. The free tier covers Python files and notebook editing and includes a code-execution trial; Juno Pro adds script, project, and notebook execution through the embedded interpreter locally and offline.

Its strongest fit is the iOS ecosystem. Juno connects with Files and iCloud Drive for file handling, PyPI for packages, and Apple Shortcuts and Siri for automation. The built-in browser includes page-source and JavaScript-console debugging tools, which can help when working with local web apps. Optional AI coding assistance is available through OpenAI, Anthropic, and Google Gemini integrations. This gives Juno a broader workflow than a notebook-only app while keeping development centered on Apple mobile devices.

The main trade-off is scope. Juno is designed for local iOS development rather than serving as a general desktop IDE, and its package manager targets pure-Python packages. That makes it a practical choice for portable scripting, learning, notebooks, and data-focused work on an iPhone or iPad. Developers who need a cross-platform desktop environment or broader project infrastructure should choose a different Python IDE. Users seeking local execution, notebook support, automation, and mobile access should find Juno the more focused option.

How long have you used it?

I've used Juno myself and this is my honest opinion — nobody paid or asked me to write it.
