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. You can chose between Jupyter notebooks and the more advance Jupyterlab using Settings. Numpy, Sympy, Matplotlib, Pandas, lxml, bokeh, nbextensions (including ipywidgets) and many other packages are pre-installed. 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. If you need scipy, seaborn or scikit-learn, please use our other App, "Carnets - Jupyter (with scipy)". 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, cryptography, cvxopt, Fiona, geopandas, geopy, lxml, matplotlib, numpy, openCV, pandas, pillow, pyFFTW, pyproj, rasterio, regex, shapely, sympy, wordcloud.
Algorithms

Verdict
The clearest difference is in-app purchases: Carnets at none against Algorithms's 3. Carnets also leads on ratings volume (316 vs 2) and chart position (#105 vs unranked). Algorithms's advantage is rating (5.0 vs 4.6) and review sentiment (100% vs 78%). On price, ads, device support and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Algorithms sells 3 one-off in-app purchases. Carnets asks for nothing beyond the download.
Algorithms holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Carnets has 316 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 78% of Carnets's written reviews are positive against 100% of Algorithms's.
Carnets ships an update monthly, Algorithms weekly. The most recent releases landed on October 13, 2026 and September 27, 2026 respectively.
