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, Polars, DuckDB, Matplotlib, SciPy, Scikit-learn, OpenCV, pygame, and more - Enjoy painless package management: install any pure Python package with an intuitive package manager AI CODING ASSISTANT The assistant runs on your account or your key, not ours: sign in with your account or 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. GAMES AND EMULATORS pygame is built in: write games with touch controls, sound, and full-screen graphics, and play them on your device. Eight complete games ship as examples, alongside NES, Game Boy, and CHIP-8 emulators written in Python, each with a library of freely licensed homebrew games — play them, then open the code to see how they work. 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. SCRIPTS AND NOTEBOOKS Python scripts (.py) get snappy, intelligent code completion, a console with a full terminal emulator, and a built-in media viewer for code-generated images, plots, and web apps. Jupyter notebooks (.ipynb) keep live code, markdown text, plots, images, and LaTeX equations in one file, with every output embedded right in the document — a perfect playground for data analysis and computational science.

Verdict
The clearest difference is review sentiment: Python IDE & Jupyter at 59% against U Game Engine + xLua's 0%. Python IDE & Jupyter also leads on price (Free vs $19.99) and ratings volume (1.1K vs 2). U Game Engine + xLua's advantage is rating (5.0 vs 4.6) and update cadence (fortnightly vs monthly). On ads, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Python IDE & Jupyter is free to download; U Game Engine + xLua costs $19.99 up front. Python IDE & Jupyter sells 1 one-off in-app purchase and U Game Engine + xLua sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
U Game Engine + xLua holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Python IDE & Jupyter has 1.1K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 59% of Python IDE & Jupyter's written reviews are positive against 0% of U Game Engine + xLua's, so the app with the better star average is not the one people write more warmly about.
Python IDE & Jupyter ships an update monthly, U Game Engine + xLua fortnightly. The most recent releases landed on October 10, 2026 and October 3, 2026 respectively.
