If you are troubleshooting an issue or have a question related to one app in particular, please check out more in-depth Q&A and troubleshooting advice for individual apps here:
If you can’t find an answer to your question:
Juno is a complete Jupyter development environment for iOS — which means it doesn’t need a server, since it runs code in your Jupyter notebooks locally, right on your iPad or iPhone. Juno Connect, on the other hand, is a Jupyter client for iOS — it lets you use same notebook editor you would find in Juno, but instead of running code on device it will use a remote Jupyter server (or cloud-computing service) as a computational backend.
Since Juno doesn’t need a server to run, it is more deeply integrated into iOS, allowing you to open Jupyter notebooks from other apps, edit them “in-place” with all changes saved in the original location, browse the working directory, and much more.
Juno Connect, being a client, connects to a remote Jupyter server instead (or cloud-computing service, such as CoCalc), giving you access to virtually unlimited computational resources of the server you are using as a backend.
There is no free trial for Juno apps; however, you can check out our app Tinkerstellar, which lets you do things similar to what Juno allows, albeit in a more limiting way.
There are no educational discounts, unfortunately: App Store doesn’t allow anything like that, and although we do participate in their Volume Purchase Program, it seems to be geared towards educational institutions rather than individual students.
If you are planning to use Juno for learning, you may be interested in our app Tinkerstellar (which is free).
Please, report all defects and feature requests in the issue tracker: Juno Issue Tracker.
Developers don’t have access to individual purchases or refunds, unfortunately — so you may need to contact App Store support directly (they have a straightforward process for this). That said, we truly hope you will give Juno apps another go some time. 😉
