Zero-setup Python IDE that runs your code offline, an AI coding assistant, and a developer toolbox — in a first-class citizen app for iPad and iPhone.
Juno is designed to cover all your Python coding needs, supporting 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 edit Jupyter notebooks in a powerful, customizable notebook editor with beautifully rendered previews — editing is free
- Write and edit code sources, scripts, JSON, XML, and other text-based formats — one versatile editor for code and text alike, with syntax highlighting
- Add quick access bookmarks for file system locations outside the app's sandbox, or simply open documents in place
PRO FEATURES
Only one thing in Juno is Pro: running code. Even that is free to try — a generous trial allowance lets you run notebooks, scripts, projects, and the REPL before you buy. After the trial, running code unlocks with a one-time Pro purchase — not a subscription.
- Run Jupyter notebooks, Python scripts, and whole projects locally with the built-in Python 3.13 interpreter and a full suite of up-to-date, preinstalled scientific and data packages — entirely offline
- Explore interactively in a Python REPL — open a standalone prompt, or drop into it after running a script or project to keep exploring what it defined
- Search the variables, functions, and imports in your session with the Object Inspector — no need to print each one
- Open any folder as a project: file tree, multiple editor tabs, run any script, with a coding assistant aware of the whole project
- Keep side outputs — Preview, Browser, Console, Object Inspector — open as side-by-side tabs in an output sidebar
- View local web servers and HTML your code produces in a built-in browser with developer debug tools
- Long-running scripts and Jupyter sessions keep going in the background
- Automate with Shortcuts and Siri: App Intents run a Python file, run Python code, or open a file — pass arguments and files, capture output, and chain actions
- Leverage powerful data analysis, machine learning and developer tools: NumPy, pandas, Matplotlib, SciPy, Scikit-learn, OpenCV, LXML, and more
- Enjoy painless package management: install any pure Python package with an intuitive package manager
AI CODING ASSISTANT
The assistant runs on your key, not ours: add your OpenAI, Anthropic, or Gemini API key, and requests go straight from your device to your provider. You control what you spend and share — Juno never takes a cut.
PYTHON MEETS iOS
Reach native iOS APIs straight from Python with the built-in juno modules: clipboard, Keychain, device info, location, motion sensors, contacts, reminders, photos, sound, notifications, sharing, and Bluetooth. Show native alerts and pickers, present full-screen image, video, and web previews, or call into UIKit, Foundation, and any Objective-C framework via the Objective-C bridge.
PYTHON SCRIPTS
Python scripts are plain-text Python source code files with a .py extension. Juno lets you work on these with snappy, intelligent code completion, a console with full terminal emulator support, and a built-in media viewer for code-generated images, plots, web apps, and more — executed by the embedded Python interpreter, locally on your iPhone or iPad and completely offline.
JUPYTER NOTEBOOKS
A Jupyter notebook is a versatile document format that stores live code, markdown text, plots, images, and LaTeX equations in a single .ipynb file. Notebooks keep a record of every input and output of an interactive session, embedding rich output (HTML, images, video, plots) right in the document — a perfect playground for data analysis, machine learning, and computational science, and Juno makes working with them a breeze!
Hey 👋, IME input should be fixed in iOS/iPadOS 13. If this doesn't work still, could you please open an issue in Juno's bug tracker? I'll be happy to help: https://github.com/rationalmatter/Juno-Issue-Tracker

사용하기에는 너무 좋아요 완벽에 가까운데 팅기지 않고 버전도 계속 업그레이드 해주면 좋겠어요

What's New in Juno 4.1.4:
HTML files now open in a live web view: pages run their JavaScript and load their own stylesheets, images, and scripts. This update also fixes installing certain packages from source, moving files in the project tree, and a range of stability issues.
Juno 4 is our biggest update yet — here's everything new.
CODING ASSISTANT
– Code alongside an AI assistant in your notebooks and scripts. Bring your own OpenAI, Anthropic, or Gemini API key and stay in full control of your data and usage.
PYTHON 3.13
– The built-in environment now runs Python 3.13, with every bundled package — NumPy, pandas, SciPy, Matplotlib, OpenCV, and more — updated along with it.
NEW WAYS TO RUN
– Python REPL: run code interactively at a prompt — standalone, or drop in after running a script or project.
– Project mode: open a folder as a project with a file tree, multiple editor tabs, and a project-aware assistant.
– Object Inspector: browse the variables, functions, and imports defined in your session.
– Output sidebar: keep previews, the console, a browser, and the inspector side by side.
PYTHON MEETS iOS
– New juno modules reach the clipboard, Keychain, device info, location, motion, contacts, reminders, photos, sound, notifications, sharing, and Bluetooth — plus native dialogs, full-screen previews, and an Objective-C bridge.
– Run Python files and code from Shortcuts and Siri, and keep long-running scripts and sessions going in the background.
MORE
– A built-in browser for local web servers and HTML, with view-source and console-log forwarding.
– One editor for code and text, with syntax highlighting and the coding assistant for both.
– Faster package search, collapsible cells, auto-scrolling notebooks, a customizable keyboard toolbar, redesigned settings, and a wide range of fixes and polish.
Editing notebooks and files is now free. Running code is a Pro feature — and you can try it, and every other Pro feature, free before you buy.
