Features & Capabilities

What is Juno?

Juno – Python and Jupyter is a zero-setup Python and data science IDE for iPad and iPhone. It natively supports Python scripts (.py) and Jupyter notebooks (.ipynb), with offline execution and a first-class coding environment.

Key capabilities

Free features include file navigation, quick notebook previews, and a versatile plain-text editor with syntax highlighting. Pro tools unlock an embedded Python 3.10 interpreter, full code completion, a terminal, Siri Shortcuts integration, and access to powerful data libraries like NumPy, Pandas, SciPy, and Matplotlib, plus an intuitive package manager.

User Reviews

Reviewers praise Juno for a tablet-optimized notebook experience on iPad with on-device data-science libraries (NumPy, pandas, Matplotlib) that support runnable code. It’s seen as strong for on-the-go data work, including lab use and Vision Pro. However, pricing is a dominant gripe: essential features require a Pro subscription, and the free tier is largely unusable. Other common complaints include it not being an IDE, awkward file navigation/editing flow, limited package management (no pip), and occasional stability issues.

Pros

Tablet-optimized notebook interface on iPad.
Bundled data-science libraries (NumPy, pandas, Matplotlib) with runnable code on-device.
Strong option for on-the-go data work (lab use and Vision Pro scenarios).
Clean, responsive UI with smooth interactions.

Cons

Paywall and pricing gating; free tier largely unusable.
Not an IDE; awkward file navigation and editing flow.
No pip support / limited package management.
Occasional stability issues.

Overall this is a great app. Opening files however is more confusing than it should be, however. For some reason tapping on a file on iPad only previews it, and for some reason the preview is always wrap rather narrowly so that there’s up to 10-20% of nothing but wasted whitespace on the right. Actually opening files results it different kinds of editors: code files get a full screen editor with a collapsible console sidebar. But text files confusingly only get a modal popup up. I understand why notebooks are somewhat different, but overall the app would be far less confusing if I could 1) actually just open files by tapping on them instead getting a useless narrow preview, and 2) just use the same editor for text and code files. Text files could just have certain toolbar items disabled. Also, I often would want to use the console or a Python terminal while viewing a text file, as some text files are actuall CSV files that I’m manipulating. The UIs in Pythonista amd Pyto are much more intuitive , but sadly development has seemed to stall for both. I’d love to replace them with Juno, but the UI needs work.

This is perfect for most data science use cases but it lacks the full capability of my main use case which is langchain. Adding this will make this app 5/5 but I am still stuck with using google colab for the IPad
