Analyse your cognitive activity on the basis of some short games. The tests are each based on four different fields: analytical skills, attention, reaction and memory. Each of the tests doesn't take more than two minutes. As a result kognitivo will depict your daily and weekly productivity in graphs and diagams which allows you to check your daily and weekly productivity.

This app is a python based android app, based on kivy framework, and it was featured on the official framework gallery. This app was downloaded amazing 400k times, most of them in Germany:

At the end of the lifetime I decided to open source the code on github and give it back to the community.
