Boost App, developed by scientists at Leibniz University Hannover and University of Lübeck, is a new educational tool designed for children's spelling based on current research findings. This app minimizes spelling mistakes effectively and operates with simplicity. Supported by the Federal Ministry of Education and Research (BMBF), Boost App makes spelling practice enjoyable and scientifically proven to be highly effective.

Boost App is self-explanatory, requiring only an initial Wi-Fi/mobile network connection. It ensures privacy by not collecting data from users or third parties. Users can create a "New Account" with a fictional name and easily log in for continuous practice. The app prompts users to input words using their finger or stylus, verifying each letter by tapping the green button for accuracy.
