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!

About

SchemaHD

This app allows users to draw circuit diagrams for logic circuits, generating Verilog HDL and performing simulations. It simplifies FPGA development by using schematics instead of complex programming languages, offering advanced security and high-performance parallel processing.

Highlights
  • Draw logic circuit diagrams
  • Generate Verilog HDL
  • Perform circuit simulations
  • Touch-based wiring
  • AXI bus interface support
  • JSON import/export
  • Offline network operation

FPGAs can dynamically generate logic circuits by means of configuration bit streams generated by languages such as Verilog and VHDL. The generated logic circuit cannot be changed by communication data. Therefore, it is very safe and cannot be attacked by hacking, which is a problem with CPUs, to execute arbitrary commands. In addition, the generated logic circuits are all running simultaneously, so the highest performance parallel processing is being performed. It can also generate logic circuits using configuration bitstreams at very high speed. Most of the processing that can be done by the CPU can be done by the FPGA alone. With advanced security and the highest performace, FPGAs are the perfect device for the modern age. However, it takes a lot of effort to learn languages such as Verilog and VHDL. There are other methods such as high-level synthesis from C/C++, but they require a lot of adjustments such as #pragma, and do not maximize the capabilities of the FPGA. Schematics, not programming languages, are needed to maximize the capabilities of FPGAs and to further improve developer productivity. Schematics allow you to grasp the whole picture at a glance, and can perfectly represent parallel processing. SchemaHD is to draw a circuit diagram of a logic circuit, and it's possible to do generation of Verilog HDL and a simulation. A made circuit diagram can be used by a different circuit diagram immediately. You can also install wiring easily by touch operation. A concept of interface is adopted as a terminal, so something structured of a AXI bus can also be used. A terminal it's also possible to distinguish sound argument reason, negative logic and characteristic wiring of a clock and a reset by interface, and which is different in interface, they don't seem able to connect, it is. You can input and output as a JSON file, so the made circuit diagram and interface are also capable of cooperation with other application. Verilog HDL generated from a circuit diagram contains a comment of a terminal name and an instance name, so it's capable of the correspondence which is at the time of problem occurrence. A network connection isn't needed, so it's also effective in information leak prevention. A simple simulation is offered in the present, but it's expected to enhance it early.

Verdict

The call

The clearest difference is rating: Python IDE & Jupyter at 4.6 against SchemaHD's 3.0. Python IDE & Jupyter also leads on ratings volume (1.1K vs 2) and chart position (#143 vs unranked). SchemaHD's advantage is monetization model (free vs freemium) and update cadence (every 10 days vs every 5 weeks). On price, ads, in-app purchases and device support there is nothing between them.
