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!
Simple Sequence Diagram AI
Read full descriptionHide full description
This app allows you to easily create sequence diagrams. Simply describe the content you want to visualize, and the latest AI technology will automatically generate the diagram for you. Visualizing with sequence diagrams is crucial for organizing complex ideas. It helps ensure that all stakeholders understand the content, making it valuable in various scenarios. However, creating such diagrams manually can be time-consuming. With this app, you can generate sequence diagrams quickly and efficiently. Even with a rough outline, the app will automatically generate a sequence diagram, and you can make detailed adjustments as needed. It is used in various situations such as: - Visualizing API communication flows in software development - Managing user registration, authentication, and service usage flows - Structuring the flow of data transmission and responses in web services - Managing and visualizing customer support inquiry processes - Designing email and notification system workflows - Visualizing interactions between microservices - Structuring complex approval workflows in business processes - Tracking user interactions in e-commerce systems - Visualizing order to delivery processes in supply chains Please try it out whenever you need to create a sequence diagram. [Features] - Intuitive operability Ease of use is the most important factor. It runs smoothly, and you can intuitively edit your maps. - Ready to use You can use it immediately without registering an account. - Multi-device support It supports Google Drive integration, allowing seamless editing across multiple devices. - Export and Share You can export and share your Flowchart, and even edit them on a PC. - Import Exported files can be imported and edited. - Text-based editing Edit your sequence diagrams directly using Mermaid notation. - Dark theme support Since it supports a dark theme, it is also ideal for use at night.

Verdict
The clearest difference is update cadence: Simple Sequence Diagram AI at every 2 weeks against Python IDE & Jupyter's every 5 weeks. Simple Sequence Diagram AI also leads on iOS requirement (15.6 vs 17.0). Python IDE & Jupyter's advantage is chart position (#126 vs unranked). On price, ads, in-app purchases and device support there is nothing between them.
