HOW SURE ARE WE
Not in any grossing chart, so this comes from ratings growth (16 new ratings a month on average since launch): revenue grows with new ratings, more slowly for apps that collect ratings fast. Tested on 418 apps with verified revenue: typically off by about 2 times, and big earners tend to come out low. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

Bugs, things not working40%

6 of the 1 and 2 star reviews.

★★★★★ Didn't work and it has bug.
★★★★★ Connecting to a instance of a Jupyter lab fails as it attempts to connect to “<server>:<server-port>/tree?” rather than /lab/tree
★★★★★ This app doesn't appear to work with Jupyter Notebooks version 7 or greater (Jupyter Lab 4). I paid for it but never got to use it I don't want to downgrade my working environment.
Missing features20%

3 of the 1 and 2 star reviews.

★★★★★ It is very frustrating to see a notebook there that I've worked an hour on and no way to save it.
★★★★★ Also missing features to set pw for a custom server
★★★★★ Maybe I'm missing something, but the app doesn't appear to be able to do anything at all (other than display its own documentation) without paying $9.99 for Pro.
Lost data, sync, backup13%

2 of the 1 and 2 star reviews.

★★★★★ I've lost work a number of times when the Juno simply can't connect to Azure Notebooks and keeps saying save failed and reconnect failed.
Worse after an update13%

★★★★★ Will update when/if i get a response
★★★★★ This app doesn't appear to work with Jupyter Notebooks version 7 or greater (Jupyter Lab 4). I paid for it but never got to use it I don't want to downgrade my working environment.
WHAT THEY ASK FOR
  • My main feature suggestion is that it might be cool to lean into the iPad's capabilities, and add an integrated drawing control to the app, for inserting quick hand-drawn sketches into a notebook. 5★, Sep 8, 2025
  • Just hope the author can add support for Notebook 7.x soon, and provide some more useful and sleek features like those in Juno. 5★, Dec 25, 2023
  • I wish we could have the ability to keep multiple notebooks open at once from different sources in tabs. 3★, Nov 25, 2020
  • I would love to see Juno work well as a more robust and native front end to that, even though I understand that Lab is still pretty new and complex. 4★, Nov 9, 2020
  • I wish that it was just one big, comprehensive pdf so that ctrl-f could solve my problems instantly. 4★, Oct 19, 2020
  • Needless to say, I wish I hadn't given them my money. 4★, Oct 13, 2019
  • You need a way to maybe send the notebook as an email attachment as a backup option when save keeps failing. 1★, Jun 17, 2019
  • Very good tool..much better than working on the iPad browser, however, I wish you can add support for Google Colab. 4★, Jan 10, 2019

6 of the 4 and 5 star reviews.

★★★★★ So far interface has been great and really looking forward to text size change integrated into the app so I can fit more text on my screen.
★★★★★ I like the clean and comfortable design.
★★★★★ The UI may not be what you're used to but the implementation is very nice.
Easy to use8%

5 of the 4 and 5 star reviews.

★★★★★ It has a more “user friendly” way of doing package management.
★★★★★ As a simple Jupyter notebook client, this works extremely well, and re-connects well to my notebook server after having a period of no activity, which has been an unexpected constant hurdle to doing real work on my new…
★★★★★ The developer's setup instructions are very straightforward and I was able to set up and connect to a remote VM with a Jupyter instance running using a Digital Ocean droplet in a matter of minutes.

love it

So useful

I like it

Now getting the hang of it

★★★★★Nov 5, 2025
Does not respond to support requests

Per the screenshots and other documentation this app natively supports integration with "cocalc" which is a type of virtual computing service. So far, i cannot find an option to add cocalc anywhere in the actual app interface- reached out twice, no response yet. Will update when/if i get a response

★★★★★Oct 31, 2025
Overall great app but some minor bugs (ipad 9th gen)

So far interface has been great and really looking forward to text size change integrated into the app so I can fit more text on my screen. I have faced some bugs in the app related to restart and run all command. Clicking this breaks the connection causing an infinite loop and disconnect and reconnect with no cells being run. Another bug has been highlighted code when in cell. I face issues with highlighting multiple lines which is kinda annoying since this seems like something really basic feature. Also faced a small issue with creating a jupyter notebook file on the server (button does not seem to work). While this might make the app seem terrible, just know even with these issues, this app has a made it a joy to take my ipad with me on the go to my classes and being able to edit, run, and create new models!!!

Elevates Jupyter and the iPad to their best selves

This is one of my favorite apps on my iPad. It takes Jupyter notebooks from being rather awkward on the iPad, to being a real joy to use. And it turns the iPad into a convenient tablet device for analysis which no other device can exactly replace. In other words, it combines these two products in a way that creates a unique and new version of each one, and it's great! My only complaint about it, really, is my fear that it will go away, because it is not popular enough to support sustained development. I hope it sticks around. My main feature suggestion is that it might be cool to lean into the iPad's capabilities, and add an integrated drawing control to the app, for inserting quick hand-drawn sketches into a notebook. This could also be a way to add equations for OCR in the notebook.

★★★★★Jul 4, 2025
Didn’t work at all

I tried to connect to my local Jupyter server using ssh fort forwarding. Didn’t work and it has bug. It can’t connect to Jupyter lab.

Store description

Juno Connect is a client app for Jupyter, a cloud-based computational environment. Juno Connect lets you leverage the computing power of a remote Jupyter server right from your iPhone or iPad. With Juno Connect you can: • Connect to cloud-computing services, such as CoCalc, Binder, SageMaker, Gradient or NAAS • Add and configure your own remote Jupyter servers • Leverage SSH tunneling with local port forwarding for secure connections • Take full advantage of your keyboard and trackpad in our full-featured code editor • Utilise full multitasking capabilities on iPad When you run code in Juno Connect, the actual computing is happening on a remote Jupyter server, giving you access to virtually unlimited computational resources from your iPhone or iPad. You can either connect to your own Jupyter server — directly via HTTP/HTTPS, or by establishing an SSH tunnel with local port forwarding — or use cloud computing services, such as CoCalc, Binder, SageMaker, Gradient or NAAS. And if you would rather execute code on device instead, check out our other app Juno, it lets you work with Jupyter notebooks autonomously on your iPhone or iPad. Juno Connect offers a full-featured notebook and code editor, providing a complete development environment on your iPad or iPhone. it supports Dark Mode and Dynamic Type, offers extended on-screen keyboard and works beautifully with all hardware keyboards and trackpads. Juno Connect lets you reach your Jupyter server easily and securely with SSH tunnel using local port forwarding. You can launch Juno Connect in Split-screen mode alongside other apps on iPad — run notebooks with documentation, terminal, or other code editor in front of you. WHAT IS JUPYTER? Jupyter is an interactive cloud-based computational environment, where you can combine code execution, rich text, mathematics, plots and rich media. It works with Jupyter notebooks, a computational document format that allows storing live code, markdown text, plots, images and equations in LaTeX — all wrapped into a single notebook file. Notebook documents keep record of all inputs and outputs of the interactive programming session, and the rich output generated by running R, Python or Julia scripts (including HTML, images, video, and plots) is embedded into the Jupyter notebook document. They are especially convenient if you are coding in Python for data analysis, machine learning, or computational science in general. A notebook consists of a sequence of cells, each representing either a narrative text in a form of markdown text or HTML, or a coding script with a text or media output. This makes notebooks both human-readable documents with the analysis description and the results (figures, tables, etc), as well as executable scripts for data analysis or plain programming. You can use Jupyter notebook as a document with optional executable code in it, or simply as a programming playground for data manipulation and experiments. Jupyter supports countless programming languages, including Python, R, Julia, and Scala. Jupyter lets you leverage big data tools, such as Apache Spark, from Python, R, and Scala — or explore that same data with pandas, scikit-learn, ggplot2, PyTorch and TensorFlow. And, of course, Juno Connect lets you use whichever language kernels and libraries are installed on your Jupyter server right on your iPhone or iPad.
