Correct spelling mistakes playfully and effectively – ideal for adults who want to improve their German spelling skills without much effort.
A wonderful learning experience for adults of varying skill levels.


Practicing the most common spelling mistakes is a very effective method and brings great benefits, as these words are frequently used and often misspelled.
For the learning effect, regular practice is crucial. Therefore, the goal was to offer an enjoyable learning experience while also integrating target-setting and intelligent training algorithms into the app.
The app's concept is largely based on self-directed learning. Adults take control of their learning process as much as possible. They set their own learning goals, organize the implementation, and evaluate their progress.
Depending on the level, the words become more complex, and the quotes and proverbs more challenging. By listening, fully writing the words, and relating them to the quote or proverb, both spelling and memory are intensely trained.
Short writing lists are designed for efficient training. Practicing one to two lists daily can be easily scheduled, becomes part of the routine, and with the Richtig-Schreiben app, it’s also a lot of fun!
Mental arithmetic structures the brain and strengthens memory. In addition, mental math can also train cognitive abilities such as concentration, working memory, logical thinking, and attention.
Staying sharp in mental arithmetic helps combat the effects of aging. It’s purely a matter of practice.
With the Master Mental Math app, we aim to provide a positive and motivating learning experience.
