Since 2013, Meister Cody GmbH and researchers from universities in Dortmund, Munich and Münster have been dedicated to the development of Meister Cody, an app-based learning game and diagnostic tool for children struggling in math and reading. Meister Cody offers a wide array of features for home, school and therapy. As of March 2018, our math assessment is #1 in the S3 Guideline for the diagnosis and treatment of dyscalculia. S3 is the highest level of scientific rigor. Our titles Talasia (Maths), Namagi (German) and Testcenter (Diagnostics) are available for mobile devices in the Google Play Store, iTunes App Store and Amazon App Store.
