Description

Zero-setup Python environment and developer toolbox in a first-class citizen app for iPad and iPhone.

Juno is designed to cover all your Python coding needs, and will work seamlessly with all source code formats. Juno supports 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 view Jupyter notebooks with quick and beautifully rendered previews
- Navigate through code sources, scripts, JSON, XML, and other text-based formats with rich previews and syntax highlighting
- Add quick access bookmarks for file system locations outside the app's sandbox, or simply open documents in place

PRO FEATURES

- Run code in Jupyter notebooks and Python sources locally on your device with a built-in Python 3.10 interpreter, entirely offline
- Write and execute Python code in a full-fledged development environment, featuring snappy, intelligent code completion and a console with full terminal emulator support
- Access all Jupyter features in a modern, powerful and customizable notebook editor
- Leverage powerful data analysis, machine learning and developer tools: NumPy, Matplotlib, SciPy, Scikit-learn, Pandas, LXML, and more
- View and edit any file as text in a built-in versatile plain text editor with syntax highlighting
- Enjoy painless package management: easily install any pure Python package with an intuitive package manager

PYTHON SCRIPTS

Python scripts are plain-text Python source code files with a .py extension. Juno lets you work on these with snappy code completion, a console with full terminal emulator support, a built-in media viewer for code-generated images, plots, web apps, and more. Juno will execute the code using an embedded Python interpreter, locally on your iPhone or iPad and completely offline.

JUPYTER NOTEBOOKS

A Jupyter notebook is a versatile document format that enables you to store live code, markdown text, plots, images, and LaTeX equations — all within a single notebook file with a .ipynb extension. Notebooks serve as excellent Python coding playgrounds for data manipulation and experimentation, and Juno makes working with them a breeze!

Notebook documents keep a record of all inputs and outputs from an interactive programming session, and the rich output generated by running Python scripts (including HTML, images, video, and plots) is embedded within the Jupyter notebook document. They are particularly convenient for coding in Python for data analysis, machine learning, or computational science in general.

What’s New

Version 3.5.0

What’s New in 3.5:

– New packages: astropy, jiter (improves compatibility with recent OpenAI package releases).
– Unpins the bokeh package, which can now be installed or upgraded in the package manager.
– Fixes several crashes and errors originating from scipy.
– Fixes a crash related to code completion.
– Addresses several minor UI and layout issues in the app.

Page Advancement

I recently started using a bluetooth keyboard with my iPad 11 pro, an I noticed that when I try to type the page advanced to the top of the screen.

Which makes it difficult to type as I’m not able to see what I type. Can this be fixed.

Developer Response ,

Apologies for a late reply — this has been resolved in the recent Juno releases.

The joy of doing Data Science on iPad

The Juno apps are by far the most helpful tools in my Data Science workflow. Since I pretty much work by myself and like the flexibility to just start prototyping an idea without having to switch back and forth between devices (and needing to carry many of them), Juno comes in very handy. I am just waiting for Scikit-learn to make it to Juno until then switching back and forth between Juno and Connect is anyway no problem. Integration with git using Working copy works like a charm (and highly recommended). Surprisingly iPad is able to handle computations very well and I haven’t struggled with the app or iPad (7th gen) resource constraints.
I see this app as a very good model for device convergence, doing such a marvellous job at putting beautiful iPad touch interface to use for service like Jupyter.
Kudos !!

Fantastic. An iPad native jupyter notebook that runs offline

Quite an impressive application. If you’re using Jupyter notebooks, it makes your iPad a lovely environment to work with them in. Everything happens on device, so you’re not connecting to a remote server that may or may not need updating, tweaking, and faffing with.

It consumes notebooks from any document storage provides on the iPad, so if a third party applications exposes storage to Files, you can work with them. The Working Copy git client provides this functionality, so you can have an iPad-based Jupyter Notebook server with git tracking working seamlessly side by side.

My only criticism is that it often seems to need to restart the running notebook when switching between applications, but this hasn’t happened so much when you have those applications running side-by-side. I suspect this is more a matter of iPad memory management than an issue with this application.

I would recommend this as a first-class Jupyter Notebook solution - probably the best way of using them on the iPad. I’m still quite astounded this exists at all, let alone how good and well integrated it is into iPad OS.
