Python IDE & Jupyter vs Haladir Wand Viewer

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.

Haladir is an independent iOS client for Weights & Biases, built by ML practitioners to keep tabs on experiments without opening a laptop. MONITOR FROM MOBILE Check training runs, scan metrics, and investigate problems without returning to your workstation. Browse projects, inspect runs, and drill into the one that's acting weird, all on your phone. KEY FEATURES • Browse Projects & Runs Navigate your projects and runs with state badges, timestamps, and key metrics at a glance. Filter by state, search by name, star projects and reports you come back to. • Interactive Training Charts Visualize metrics with auto-refreshing charts that update while the run is live. Metrics are grouped automatically by prefix (train/, val/, loss, accuracy) so you don't hunt for what you want. • Logs with Severity Coloring A dedicated logs viewer surfaces WARN, ERROR, and DEBUG lines in distinct colors. Tail-follow, load older, filter by severity or time, search inline. • Run Comparison Long-press a run to start a selection, pick up to five, and overlay their metric charts side-by-side to analyze ablations. • Sweep Tracking View sweep configs, the best run so far, and all agent runs in one place. • System Monitoring Track GPU utilization, CPU usage, memory, disk, and network as real charts per device, with a tunable sampling resolution. • Artifacts & Files Browse artifacts with versions and aliases. Preview files inline: images, videos, JSON (syntax-highlighted), wandb.Table, CSVs (as text), and text with pinch-zoom. • Reports Browse your Weights & Biases reports and open them in one tap. • Run Environment Git SHA, Python version, GPU type, OS, all one tap from the overview. • Ten Color Palettes Classic Dark/Light, Sepia, Mocha, Ember, Gruvbox, Everforest, Rosé Pine, Catppuccin Mocha, and High Contrast Dark. • Offline Cache Recently viewed runs stay readable without a connection. An unobtrusive banner tells you when data is stale. • Team Entities Switch between your personal entity and any team you're a member of. SECURE & PRIVATE Your API key is stored in the iOS Keychain, the same technology that protects your passwords. Credentials never leave your device except to communicate with the official Weights & Biases API. No third-party servers, no analytics SDKs, no crash reporting. DESIGNED FOR ML ENGINEERS Built by ML practitioners who understand the workflow. The interface is tuned for quick checks and mid-meeting glances, not to replace the full web dashboard. REQUIREMENTS - A Weights & Biases account (free tier works) - A Weights & Biases API key (get it from wandb.ai/authorize) Haladir is an independent app and is not affiliated with or endorsed by Weights & Biases, Inc.
