"Juno has completely transformed my iPad Pro into a legitimate data science workstation. Being able to run NumPy and Pandas locally and offline while commuting is a total game-changer for my workflow. It is the first app that makes Python feel like a first-class citizen on iOS, and the interface is incredibly polished."

Alex Chen, Senior Data Analyst

"As a Computer Science student, I needed a way to practice coding and work on my Jupyter notebooks without lugging my laptop everywhere. Juno’s zero-setup environment is perfect—I can jump straight into my .ipynb files and see beautiful plots and renders instantly. It is easily the best investment I have made for my studies."

About the app

Everything you need to know about Juno – Python and Jupyter.

Description

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 - View and edit code sources, scripts, JSON, XML, and other text-based formats in a built-in versatile plain text editor with 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 3.10 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 - Works with Siri: create Shortcuts that run Python code or .py scripts in Juno—pass arguments and files, capture output and chain actions - Leverage powerful data analysis, machine learning and developer tools: NumPy, Matplotlib, SciPy, Scikit-learn, Pandas, LXML, and more - 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.
