This app is intended for anyone who wants to improve their computing performance. Various settings give you the opportunity to adjust the level of difficulty to your ability. Depending on your wishes, the arithmetic operations can be selected. The questions are read out so that the questions can be recorded on various visual channels.
A log records how long, how many invoices were solved and which invoices were solved incorrectly. Play with the settings and try to get as far as possible.

The log is saved in the cell phone. The log can only be read using the app. The rights have been set up accordingly. The data from the protocol is neither forwarded nor evaluated in any form. The data belongs solely to the owner of the protocol.

This app was created as part of a module work at PH-Bern on the topic of inclusion and as a special exercise aid for children with dyscalculia.
