About this app

This app aims to enable digital exercise book management for school lessons. I started programming it many years ago because I couldn't find an app for my geometry lessons that allowed me to carry out constructions like in a school exercise book. The focus of the app is on creating exercise book entries, just as you would with an analogue exercise book and the usual utensils you have in your pencil case. Accordingly, there are no countless setting options that only distract and waste time. All exercise books are saved locally on the device and no usage data is collected so that the app can also be used in a school environment in compliance with data protection regulations. The app can be used free of charge without annoying adverts. Since 2025, however, it has also been possible to support the development of the app financially.

Ratings and reviews

Found what I have been searching for. This is just the right app if you want to make explainer videos of geometry and trigonometry. It has all the geometrical tools. You can draw all the mathematical graphs, functions etc., And guess what!! You have recording option too. Thats fantastic. Loved it totally.

Different grid formats (cell, line), different thickness, transparency and colors palette - all well, such instruments as L-square and compass - excellent, but absence of undo button and German GUI only- bad. 4 stars because of 2 last factors. If developers add this functions all will be excellent. Also it would be great if developers would add such instruments as vector line, triangle,cercle and rectangle

If the zoom and adding photo option was there i would give it 5 star. Here is a trick for zooming》》 Go to settings 》accessibility 》turn on magnification. U can zoom anywhere you want. Except that it's a wonderful app. It is even helpful for students. I am a student.Thanks for reading.
