Zero-setup Python environment and developer toolbox in a first-class citizen app for iPad and iPhone.
Juno is designed to cover all your Python coding needs, and will work seamlessly with all source code formats. Juno supports both Python scripts (.py) and Jupyter notebooks (.ipynb) — a document format focused on applying Python to data analysis and computational science.
FREE FEATURES
- Navigate and manage files and folders, quickly preview documents and media
- Browse and view Jupyter notebooks with quick and beautifully rendered previews
- Navigate through code sources, scripts, JSON, XML, and other text-based formats with rich previews and syntax highlighting
- Add quick access bookmarks for file system locations outside the app's sandbox, or simply open documents in place
PRO FEATURES
- Run code in Jupyter notebooks and Python sources locally on your device with a built-in Python interpreter, entirely offline
- Write and execute Python code in a full-fledged development environment, featuring snappy, intelligent code completion and a console with full terminal emulator support
- Access all Jupyter features in a modern, powerful and customizable notebook editor
- Leverage powerful data analysis, machine learning and developer tools: NumPy, Matplotlib, SciPy, Scikit-learn, Pandas, LXML, and more
- View and edit any file as text in a built-in versatile plain text editor with syntax highlighting
- Enjoy painless package management: easily install any pure Python package with an intuitive package manager
PYTHON SCRIPTS
Python scripts are plain-text Python source code files with a .py extension. Juno lets you work on these with snappy code completion, a console with full terminal emulator support, a built-in media viewer for code-generated images, plots, web apps, and more. Juno will execute the code using an embedded Python interpreter, locally on your iPhone or iPad and completely offline.
JUPYTER NOTEBOOKS
A Jupyter notebook is a versatile document format that enables you to store live code, markdown text, plots, images, and LaTeX equations — all within a single notebook file with a .ipynb extension. Notebooks serve as excellent Python coding playgrounds for data manipulation and experimentation, and Juno makes working with them a breeze!
Notebook documents keep a record of all inputs and outputs from an interactive programming session, and the rich output generated by running Python scripts (including HTML, images, video, and plots) is embedded within the Jupyter notebook document. They are particularly convenient for coding in Python for data analysis, machine learning, or computational science in general.

Juno – Python and Jupyter version 1.5.3
Updated At: 2022-08-21
Changes: Aug 21, 2022 Version 1.5.3
Fixes a couple of minor UI issues.
Juno – Python and Jupyter version 1.5.2
Updated At: 2022-05-05
Changes: May 5, 2022 Version 1.5.2
Juno 1.5 comes with a package manager on board! It has a ton of quality of life improvements: you can see all packages that are available to you, both system and user installed; you can delete user-installed packages and install new ones; there is now an easy way to see which dependencies are missing or have incompatible versions, which package releases are likely to work in Juno and which modules the package provides - among many other things!
Juno's package manager introduces a concept of *pinned* packages: you can import and use those as any other package, but you can't upgrade or delete them (as Juno relies on them under-the-hood).
Finally, we've made a bunch of improvements to the package installation process, so Juno can now handle several older-style distribution formats. That said, what you can install is still constrained by the OS restrictions, which means pure Python packages only.
Juno – Python and Jupyter version 1.4.2
Updated At: 2022-03-17
Changes: Mar 17, 2022 Version 1.4.2
- Multi-window support for iPadOS! You can now edit and run multiple notebooks simultaneously on iPad, each in a separate Juno window - including side-by-side in Split View.
- Improved context restoration, working directory management and a few other things, which needed to accommodate this new multi-window nature of Juno.
- Package installer can now process several older-style distribution formats.
- Fixes for a couple of bugs around file system access.
- Fixes for several minor UI issues.
- Many under-the-hood changes and improvements, which lay important groundwork for future Juno features: this release is just one of a few major updates coming this year. Keep your eyes peeled and follow us on Twitter for more details!
