Juno
reviews and complaints

It’s the best version of what it does, hands down.

Just leaving this review because after several months of great use, I ran into the first bug. Latest version, as it was offloaded by iCloud and just finished re-downloading. It immediately would crash on my iPhone XS, Black.

I deleted and reinstalled… It’s fixed now. Great work guys!

This is a great tool. Well worth the money. The one problem I have is it doesn’t persist in memory very well when switching apps. When returning to this app, it has to reload, playing the splash screen, and lands you at the file browser window. It doesn’t even reopen the notebook you were working in. Very annoying.

Other than that, I find it to be solid and highly useful.

This thing is absolutely amazing. I’m very much a beginner/amateur, never used Jupyter, and know just enough python to frustrate myself with the potential and possibility. Having this on an iPad, and so functionally well contained, it has been a pure delight for a simpleton such as myself. My python learning is finally starting to stick. I’m addicted!

(This isn’t to say you can’t do powerful advanced things, I just wouldn’t know, lol)

The recent update to 1.2.8 has completely destroyed the utility of this app. Not only did it wipe out all my notebooks and time-consuming painstaking installation of MANY pure python pypi packages for my notebooks, but upon uninstall/reinstall it doesn’t create its base set of files and thus I can’t even begin again. New notebooks cannot be created or executed.

Will revise upon developer resolution of this massive issue. Before this it was an awesome tool.

Pythonista, which I also have, was ahead of its time. However, it really didn't keep up.

Juno is the golden standard now, nothing short of revolutionary. It puts an entire Python scientific and ML development environment in your device, including a Python interpreter, Jupyter, NumPy, Matplotlib, Pandas, SciPy, Scikit-learn and a few other libraries and packages. Oh, plus the capability to install additional pure Python libraries, such as SymPy.

Fantastic and highly recommended.

This app really increases iPad productivity and power. Nothing really says a powerful tablet like being able to write scripts on it, and this app enables the tablet to be just that. Just tag on a keyboard and you’re basically using a laptop. It has a great layout and is extremely intuitive and well built.

HOWEVER, whenever I want to switch between other apps for referencing (which is often), I find that I have to wait for Juno to “boot up” again. The app boots up really fast, so this issue is really more of an annoyance than an inconvenience. Aside from that small issue, it is 5/5!

I never leave reviews, but I had to leave one for this app. It is absolutely incredible, and might even allow me to finally get rid of my laptop for good!

I use Jupyter notebooks as a data scientist in the public policy sector. We’re visualization-driven, so being able to install my favorite packages like plotly and geopandas was a must. Juno SOMEHOW allows you to install python packages — I was blown away — and that makes it all work perfectly! I imported a notebook I’d been recently working on, and I didn’t have to change a single line of code in order to get it working on my iPad Pro; it just worked!

Like I said, amazing app. 100% worth it. Plus, if you care about design at all, you’ll appreciate Juno’s UI — so much nicer looking than jupyter notebooks on Mac. Amazing!

This app seems great. I often need to test small pieces of code out as I’m working on bigger projects. It’s really convenient to do this on my iPad because it’s so portable. I found Juno and immediately bought it. It was a perfect solution for me. I dug in and started working some prototyping with Numpy and SciPy. I quickly discovered that Juno “pins” specific packages which means they cannot be deleted or UPGRADED. Numpy was several minor releases behind as well as pandas. The functions I needed from their APIs is in newer releases. This was a total surprise to me and it really presents some limitations in what I can do. I think Juno is a great concept and the interface/layout/setup seems well done. I’m not sure how useful it will be to me in the long run if it tails behind current releases for common packages by such a margin. It would be great if there was a way to vote or provide some input for needing packages so that the company might be able to prioritize releasing them better. I do see Juno Connect as an offering as well unfortunately it will mean setting up a Jupyter server and then at that point I’m having to maintain that somehow too. Not ideal.

Update: the developer is very responsive to feedback and is understanding if technical issues which is greatly appreciated.

It doesn’t work. You can get your stuff running. Native IPad OS blocks everything!

You gave incorrect response to my submission

I try again, it crashes when opening

I use a lot of print statements to debug my code, and with no command prompts I can’t debug my code easily

It’s running python 3.6! This is a 6 year old version of python that was end of supported in Dec 2021. How can you in good faith sell this in Sep 22 for $14.99 without disclosing that! It’s a toy at best a scam at worst. Please refund.
