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.

Terrible keyboard shortcuts. No vim mode. It’s honestly just awful to work with. Skip it. Use a laptop.

Worth the $40 to use this app. However with latest builds, clicking cell output with plots doesn’t use screen wisely. on 12.9 in ipad, it pops up a 400 x 400 window that takes up less 25% of screen width and height. Zooming is awkward to use. Until developers fix, i’m going use my laptop
