Juno Connect: Jupyter Client 17+

Cloud Coding/Programming IDE

Designed for iPad

    • £9.99



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.


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.

It’s like a dream come true!

Having recently started using Jupyter on my Mac, I was excited to see that access to all my notes are readily available on my Phone! Amazing! It’s such a polished app and still offers all the features I’ve come to love using! Highly recommended to all Jupyter users! ⭐️⭐️⭐️⭐️⭐️

This app is not meaningless after all

Edit: I think my previous review was too harsh. The nicer looking and more touch friendly interface is still valuable.

Initial review:
Jupyter notebook has a web based front end. You can connect to your Jupyter notebook server directly in Safari. This app does not provide anything extra beside a sleeker look. It also lacks in features compared to the full interface in web. For example, in the use of Azure notebook, there is no way to download or upload files from the server in the app while you can in Safari.

I think this app should at least provide the same functionalities to compete with Safari.

Developer Response ,

Juno provides a lot on top of what Safari has to offer: its user interface is optimised for touch devices and mobile screens, Juno has full hardware keyboard support (including Jupyter shortcuts), as well as extended onscreen keyboard for code editing. Juno provides code completion driven by your server's kernel, which is not available in Safari, and much more. As per Azure Notebooks integration — this service is still in preview, so unfortunately there are only so many things that we can integrate with them at this stage.

Either way, we're sorry you don't see much value in Juno, so feel free to request a refund if you purchased Juno Pro. But we truly hope you will reconsider and give it another shot at some point! Also, please reach out to feedback@juno.sh if you have any suggestions or feature requests.

Finally on the iPhone!!!

I can finally use Jupyter on my iPad! Having access on iPhone is usefull too, although probably something I won’t use much. Since Jupyter is barely usable in iPad’s Safari, Juno is a HUGE improvement to my workflow, and is totally worth the investment.
