Juno Connect: Jupyter Client

Juno is a client app for Jupyter, an interactive cloud-based computational environment, where you can combine code execution, rich text, mathematics, plots and rich media.

CLOUD COMPUTING
When you write code in Juno, the actual computing is happenning on a remote Jupyter server, giving you access to virtually unlimited computational resources from your iPhone or iPad. Juno lets you connect to your own Jupyter server, or use cloud computing services, such as CoCalc and Azure Notebooks.

JUPYTER NOTEBOOK
• Jupyter Notebook has support for over 40 programming languages, including Python, R, Julia and Scala.
• Produce rich output with your code: HTML, images, videos, LaTeX, and custom MIME types, all wrapped into a single notebook file.
• Leverage big data tools, such as Apache Spark, from Python, R and Scala. Explore that same data with pandas, scikit-learn, ggplot2, TensorFlow.

JUNO FEATURES AT A GLANCE
• Optimizing Jupyter for iOS, Juno delivers a full-featured code editor experience and a complete development environment on your iPhone or iPad.
• Use all familiar Jupyter shortcuts with your external hardware keyboard.
• Launch Juno in Split-screen mode alongside other apps on iPad. Run notebooks with documentation, terminal, or other code editor in front of you.
• Get code completion suggestions for your programming language as you type, powered by your Jupyter Notebook server's kernel.
• Try Jupyter without any preliminary configuration. We have bundled introductory notebooks on Python, Matplotlib, NumPy, SciPy — and will keep adding more!

Reviews

Nice implementation, but little utility
Centus

For practitioners of AI, this app holds promise, but no utility. Please implement interfaces to Google COLAB, Kaggle, AWS, and other GPU-based platforms

Well worth the money

I needed to be able to do some work on my iPad so I took a chance with Juno Connect. It works great, better than I expected. I’m using it with my Magic Keyboard and it feels like I’m back at my laptop. Connecting to a private Jupyter server over SSH was remarkably stable.

Another dimension for Jupyter notebooks

Excellent software, iPad experience better than web experience.

Works reliably
usernamewastaken1123

*Original review:* Hard to find any good documentation. What is within the app as well as on the faqs and docs pages online is not helpful. I found my way through by creating new connections until I felt like I understood how things work. But deleting and editing current connections appears to be impossible, so I had to reinstall the app to clean up the interface. But once you get it working it will be quite reliable. *Edit:* After about two weeks, I was contacted by a developer. There is a way to delete and edit existing servers: either swipe the servers list or view connection details. Finding documentation of this is still difficult. Because I was directly contacted and notified that my issue was a matter of ignorance, I changed the review from 3 stars to 4 stars. I would move the to 5 stars if I could easily find the Juno documentation describing precisely how to edit or delete servers. The documentation is the worst part of this app. I wish that it was just one big, comprehensive pdf so that ctrl-f could solve my problems instantly. I have had no other issues with this app. Once set up, the app is a pleasure to use. Browser-based notebooks are a thing of the past on this iPad.

Fantastic app, very easy setup
Remmy909

I’m a data science grad student and this app has been super useful and fun to use when I am bored of using my laptop. 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. I also was able to setup a connection to my own laptop, but dislike having to launch/shutdown the server and prefer the constant access of the remote server. It’s great to have those options. The app has been very reliable for me so far. Thanks and keep up the great work!!

Very good for what it is, would love more Lab integration

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 iPad Pro. I hope that the developer continues to do work on this and push towards more full Jupyter Lab integration, because I’m now starting to lean towards running Lab in a browser to get some of the more advanced features (including its very good Python text editor and git integration). 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.

Please allow multiple tabs open
AlecTar

I have numerous notebooks from a variety of servers I’m SSHing into, and it is extremely inconvenient to have to close the notebook I’m currently working on to access another notebook, especially as it terminates all the output writing to the cell console when I go back to the notebook. I wish we could have the ability to keep multiple notebooks open at once from different sources in tabs.

No support for Jupyter Lab?

O native notebook editor. Just a $10 web-browser for my Jupyter Lab instance.

Amazing with Raspberry Pi
latinoheat8908

I love using my iPad as much as possible, but the one downside is that it doesn't work with non-pure Python libraries natively. I installed a JupyterHub instance on my Raspberry Pi and can now use Juno Connect to connect to it seamlessly. Works like a dream!
