Each path starts with a baseline test, followed by a series of guided exercises. Every eight sessions, you take the test again. This cycle continues as you work toward your goals. You can also explore the exercises freely in the Lab.
The collection includes classic Dual N-Back and several reworkings of it, alongside Operation Span, Stroop, object tracking, and puzzles such as Gridlock (a Rush Hour-style sliding puzzle), Untangle, Sokoban, and Lights Out. There are over 30 configurable exercises.
The scores track performance on these tasks; they aren't IQ estimates or a promise of broader cognitive gains.
You can try it in your browser without an account. It is also available on Android. The full app has a 90-minute free trial, then a one-time €6.99 unlock, with no subscription.
