iOS Unfitted
Juno is one of the most elegant IDEs I have ever encountered. However, using an iPhone to do coding on Juno won’t release the full potential of this app since editing and debugging on a small touchscreen is not efficient.
APP IS NOT FREE
Dumbest app ever if I can’t run my code for free then what’s the point of the app… then they respond saying that running code is not free Whats nonsense what does ot take to run a Piece of code.. Nkwasiasem

Suggestions for Potential Downloaders
Juno is one of the most elegant IDEs I have ever encountered - second only to IDLE or Sublime Text. However, using an iPhone to do coding on Juno won’t release the full potential of this app since editing and debugging on a small touchscreen is not efficient. But if you’re using an iPad, especially a 13-inch model? Pretend I haven’t said anything yet.

Excellent tool!!! This review is for 4.3.2
I love Juno!!! This is one of the best tools in the App Store. I recently experienced performance issues with the previous release. I contacted the Juno team with sample performance data. They replied right away, fixed the issue and to my pleasure I downloaded the new update today from the App Store and my code flies. Great app, great team behind it, definitely five stars. Thank you!

It’s fine but the UX is the worst
Terrible keyboard shortcuts. No vim mode. It’s honestly just awful to work with. Skip it. Use a laptop.
Can’t use Plotly Dash no more
Would appreciate you fixing whatever’s missing that dash doesn’t run anymore
Response from developer
Hi 👋—please reach out to help@juno so that I can investigate this further. Thanks!
为我之前的评论感到抱歉
这是一个非常好的学习和使用Python的工具软件，但因为我的无知（因为我最开始没有看到回复购买的选项）给这个App打了一星，现在我希望收回之前的评价，也同时感谢开发者这几年还在不断更新这个App。再次为我的错误向开发者朋友道歉🙇
Response from developer
👋 你好！Juno 只需付费一次——此前购买过任何版本的用户，都应该已经免费解锁了全部付费功能。如果没有自动解锁，请发邮件至 help@juno.sh，我会帮你查看。 👋 Hey—you only pay once; everyone who had ever purchased any version of Juno previously should have all paid features unlocked for free. If this didn’t happen automatically please reach out to help@juno.sh and I’ll take a look.
Worth every penny - now supports Claude, Codex and OpenCode
Now works with your AI subscriptions, including Claude, Codex and OpenCode (and anything with compatible API), brilliant thank you! Previous review from 2025: I got this for arbitrary precision maths using mpmath (and SymPy) and it’s great, worth every penny. Only certain libraries are available because of the locked-down iOS platform, but that includes lots of favourites. This sole developer is doing a superb job!

Worth every penny - needs OpenCode AI!
AI integration would be much better with more model support, eg OpenCode.

Cell Output Plots
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
Positively answered a long time search of mine
Yes, I had been searching for an app that would give a CAS, a programming language and the possibility of porting my files to my macbook.
I tryed several until I found python in ios.
I took some time until I decided to give juno a try. I am very satisfied.
The package numpy sometimes gets unload by the OS,as explained by the developer, but I can manage.
The developer even answers our questions, which is nice!

Incredible tool
This is what is currently possible in iOS / iPadOS. Great product.

Amazing!
I’ve used Juno for years and am so happy to shout out these developers. There is consistent support and updates to the app and to the underlying libraries. Juno is actually my main daily Jupyter notebook and code editor. It’s amazing to have it available wherever I am and I can achieve so much with it. The most recent updates have been even more of a game changer. With projects and AI assistants, as well as full utilization of background processes, there is so much more that can be done. Worth every penny. Please keep up the great work and great support!

Amazing Python/Jupyter on iPad
I could never imagine one day I can lie on sofa to script Python. Now I did it with this wonderful App :)
Great app
I really like the app, it is probably the best way to do Jupyter on the Ipad.
💝
Juno is the best.
Nice to have Jupyter notebooks on my iPad
Overall the running of Python scripts and Jupyter notebooks works very well. In fact, the app would be worth the money just for the Jupyter notebooks. However, the user experience for me was a bit of a let down. I keep getting little problems like auto indents going to the wrong place, eapecially after two finger cursor moving gestures over the keyboard, and sometimes the cursor going off a few lines when I tap to place the cursor, which require me to exit and reopen the app. Plus navigating back to the project/file list can be unintuitive and frustrating especially in portrait view (perhaps because I have an iPad Mini). I do like this app though, I just think the dev could spend a bit more time coding with it so it becomes a bit more polished.
