Build an open source math, memory and focus improvement app. The app itself consists of a bunch of small games. Right now I try to keep the games as simple as possible to allow the implementation for the terminal client.
This project is open-source and maintained by a single developer. If you find this app useful, please consider sponsoring to help take it to the next level with more features and faster updates.
Very welcome.
