PraktiCalc is an unique calculator with many features you see elsewhere, and some you only get here. Development is happening on GitHub at the time of writing. If you have any issues or feature ideas, please let me know by opening an issue on GitHub (you can also open a ticket here if you want, but I don't look at them that often).
There are packages for Windows (x86_64), macOS (aarch64) and Linux (Debian, AppImages for amd64/aarch64, TinyCore).
