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!
MQTT Checker
Read full descriptionHide full description
MQTT Checker is an amazingly simple application that quickly checks MQTT connections. This app helps users swiftly verify their ability to connect to MQTT servers. Users can easily input essential information such as ServerUrl or IP and ServerPort, and optionally configure ClientID, Broker Name, Topic, and Message. Key Features: Swift MQTT Server Connection Verification: MQTT Checker swiftly confirms the ability to connect to MQTT servers by allowing users to input ServerUrl or IP and ServerPort through a user-friendly interface. Additional Configuration Options: Optionally set ClientID, Broker Name, Topic, and Message to tailor MQTT connection tests to your preferences. Concise Notifications: Upon successful connection to the MQTT server, clear and concise notifications inform users. Error Messages on Failure: In case of failed MQTT server connections, display error messages to quickly identify issues.

Verdict
The clearest difference is in-app purchases: MQTT Checker at none against Python IDE & Jupyter's 1. MQTT Checker also leads on iOS requirement (12.0 vs 17.0). Python IDE & Jupyter's advantage is chart position (#129 vs unranked). On price, update cadence, ads and device support there is nothing between them.
