## What is Carnets?

Jupyter notebooks are a powerful tool used in education and research. You can write small snippets of Python code and observe the result on screen, combine with paragraphs of text, using Markdown.

Carnets provides a complete, stand-alone, implementation of Jupyter notebooks. Everything runs on your device, using the embedded Python interpreter; you do not need an internet connection. Compared to the standard version (Carnets), this app adds several packages targeted for scientific computation and learning: scipy, sklearn, seaborn and coremltools. You can switch between standard notebooks and the more modern jupyterlab using the Settings app. 

Of course, all the packages included with the standard app are present too: numpy, simply, matplotlib... To see the full list of installed packages, type "%pip list" in a code window. You can add more packages using "%pip install packageName", but only if they are pure Python.

You can share your notebooks with other apps and also open notebooks or directories managed by other apps. 

Partial list of installed packages: astropy, babel, bokeh, cartopy, cryptography, cvxopt, Fiona, geopandas, geopy, gym, inequality, libpysal, lxml, mapclassify, matplotlib, networkx, nltk, numpy, openCV, pandas, parso, pillow, pyFFTW, pyproj, qutip, rasterio, regex, Rtree, scikit-learn, scipy, seaborn, segregation, shapely, soupsieve, spopt, statsmodels, sympy, wordcloud.

### 3/5 — Très instructif

*2026-04-18*

Par contre le développement et la stabilité est encore à améliorer.

### 5/5 — Best Python Editor for iPadOS

*2025-12-11*

Awesome app with JupyterLab support. You must try and you won’t be disappointed,

### 5/5 — Best python coding app in apple store

*2025-12-10, version 1.9.1*

I LIKE IT Y(^_^)Y

### 3/5 — Problème avec le clavier Apple iPad Magic Keyboard

*2025-11-19*

Petit problème depuis la dernière mise à jour: les combinaisons de touches  `Option+(` et  `Option+)` ne fonctionnent plus (elles devraient afficher les caractères `{` et `}`), alors qu’elles fonctionnent correctement dans les autres écrans de saisie (comme celui-ci)

**Developer response:** Merci d’avoir signalé ce problème. Ça devrait être  réglé dans la version 1.9.1.

### 4/5 — Improved

*2025-11-10*

I tested today. The issue with the battery seems to be gone. I used for a few hours without any appreciable drainage of the battery. I will continue testing for a few days.

### 5/5 — Good App

*2025-10-07*

Complete and well organized. 
Thank you

### 4/5 — A surprise for how much I have enjoyed this

*2025-10-02, version 1.8.4*

As a CS student who wants to focus in machine learning and does part-time research in the field. I have absolutely loved using this for on-the-go coding on my ipad. What has surprised me the most is the support for so many packages that I use on a daily basis. My only wish for the app that keeps it from being perfect is not being able to ssh into other machines to run my jupyter code. While I can run most basic ML projects on my iPad, there is some research code that would make it massively easier to run through a remote machine. Hopefully this could be a feature added in the feature or even a different app if that is easier for the developer.

### 5/5 — Just Started Using but Amazing!

*2025-09-19*

Works for everything I need.

### 5/5 — 顶上去啊真好用

*2025-08-27*

在学校学的jupyterlab然后就找到了这个软件，爱不释手手机上随时随地可以跑代码还有scipy。代替计算器。

### 2/5 — Makes my iPhone 16 physically hot to the touch

*2025-05-05, version 1.8.4*

Running this application actually makes my iPhone 16 Pro quite hot to the touch.  Not sure why.  Several apps do this but no crashes or suggestion of issues apart from the heat.
