5/5Love this app! You should charge good money for it!
This is a fabulous Jupiter implementation and allows me to do development on the road when not connected to the server on my corporate network. My only complaint: Full file access only appears to work from the Carnets app folder. If I go to a Working Copy folder (ideal for git access) I can only open ipynb files, and modules, data files, etc. don’t load. If I copy a Working Copy folder into the Carnets folder, everything works perfectly. Would love to see this issue fixed, then I’d give you 6 stars (if Apple would allow it).

5/5Absolutely awesome
I have been hoping for local Jupyter notebooks on the iPad for a long time, thank for creating this. I am going to disagree with other reviewers and say don’t worry about remote for now, Juno and Working Copy have that solved. Keep working on making offline local Notebooks better, that is the problem only you are solving. And please charge for the app, I really want you to keep making this better and will gladly pay.

5/5Awesome app! Problem with turtle package though . . .
This app is fantastic!! I definitely recommend it. It is definitely helping with learning Python. Though every time I try to draw something with turtle package, it says it couldn’t find it. It always says there’s something wrong with import turtle. Will you please look into this?

4/5Great App, except ONE issue
I really wish there was an option to fill in the ipad screen. When using landscape mode, there is considerable space to left and right that aren't being used, this combined with text being small (without any option to resize), makes it feel cramped. Really wish there was a mode where it would be more zoomed in (so no wasted blank space on left/right side), possibly where some of the meny bar item up avove slide away, so more of the coding canvas fills the screen. Since ipads are smaller than laptops, this would make such a big difference. Also, add a donate button in the app if you can. Its free, so its great, but i would honesly donate 10 bucks if i could, many more probably would too.

3/5Great app needs some work
I am not someone to write long reviews but here we are. By itself this app is great but certain data types never work and functions are considered syntax errors I checked over and over to see what I was doing wrong for an hour around but still nothing and other functions seemed to be non existent so please fix this because this a great app but needs some work also way to many adds.

Versions

App Store

1.5.7
- fixed an issue with the cell_filter nbextension. - fixed a crash that happened if the kernel was restarted too many times.
1.5.8
New Python modules: nltk, regex, wordcloud, cvxopt, pyFFTW.
1.6.0
Fixes the issue with carriage return on external keyboards and iOS 15.
1.6.1
- new python modules: OpenCV, geopandas, shapely... - adds several keyboard shortcuts
1.6.2
- fixed a bug with astropy - updated Python version to 3.9.8 - improved file management, display an alert when we can't save a file - updated packages to their latest version: matplotlib 3.4.0, numpy 1.22, pandas 1.3.4, astropy 5.0...
1.6.3
- virtual environments for Python. Create with "!python -m venv newEnvironment", activate with "%run newEnvironment/bin/activate.py", deactivate with "%run newEnvironment/bin/deactivate.py". Virtual environments are limited to user-installed packages, and are only activated for the current notebook. - added ffmpeg as an external command, for use with OpenCV. - Command + return on external keyboards now executes the current cell without moving the insertion point (as opposed to Option + return, which executes the current cell and create a new cell below).
1.6.4
- fixes a bug with "%pip install" that affected some pure Python packages.
1.6.5
- fixes a bug with virtual environments.
1.6.6
- fixes an issue with virtual environments
1.7.0
- better at opening files in other apps directories, with explicit warning if Carnets does not have access to the directory. - you can chose your notebook style: classical notebook, nbclassic or retrolab (soon to be notebook v7). Pick the style you want using the Settings app, it will be active at the next app restart. - retrolab is better for small screens, has more translations available and lets you chose dark or light theme independently of the iOS dark or light mode. - from retrolab, you can switch to jupyterlab if you want. Jupyterlab works better if you have an external mouse. - fixes a bug with virtual environments
1.7.1
- fixes the crash issue on iOS 14 - better contrast for the toolbar at the bottom when using external keyboard - fixes an issue with "download as" for notebook and nbclassic (jupyterlab & retrolab were not affected) - better information when using virtual environments - always reset jupyterlab, to avoid issues - updated jupyter-server to the latest version - several fixes to make Carnets more robust
1.7.2
- updated packages to their most recent version. This solves the issue with .describe() in pandas. - numpy 1.24, matplotlib 3.5.2, pandas 1.4.2, astropy 5.1...
1.7.4
- updated Python version to 3.11 - updated packages to their latest version - fixed several issues with "Download as..." - fixed issues with Matplotlib and fonts - Notebook and NbClassic now share the same JavaScript code - Many bug fixes
1.7.5
- updated Python version to 3.11 - updated packages to their latest version - fixed several issues with "Download as..." - fixed issues with Matplotlib and fonts - Notebook and NbClassic now share the same JavaScript code - Many bug fixes, including a bug introduced with 1.7.4 and Pandas.
1.7.6

1.7.9
- new module: lzma - new keyboard shortcuts for forward one page / backward one page (shift-command-[ / shift-command-])
1.8.0
- Updated to Notebooks v7: better user interface, more translations, better stability, fewer issues. - Updated packages to their latest version. - New "home" button : gets you straight back to the file browser.
1.8.1
- fixed issues with Matplotlib - fixed issues with iCloud access - makes sure notebooks are saved when you go back to the file browser.
1.8.2
- fixed issues with Matplotlib - fixed issues with iCloud access - fixed issue with "File -> New" - makes sure notebooks are saved when you go back to the file browser.
1.8.3
- fixed a major issue with iCloud drive access.
1.8.4
Do not show an alert about iCloud access if the user does not have an iCloud account.
1.9.0
- Reduced battery and CPU consumption; this should fix the overheating issues. - Updated Python to version 3.13 - updated all major packages to the latest version (numpy, matplotlib, ...) - better user interface on small devices (iPhones, or small windows on iPads) - multiple bug fixes.
