Better Brain is a lifestyle application designed to boost your fluid intelligence through challenging memory tasks. By engaging in exercises that involve remembering audio and visual events simultaneously, users can enhance their ability to reason and solve problems independently of previous knowledge. A recent scientific study has demonstrated the positive impact of this training on the fluid intelligence of participants.

One of the key tasks in Better Brain is the 2-back task, where users must recall a letter heard two steps back and the position of a square on a grid. The app offers customizable settings, including two additional training tasks and adaptive difficulty levels. Users can progress to the more demanding 3-back task as they improve, and the difficulty level adjusts based on performance. Better Brain also allows users to practice dual-channel memory tasks, focusing on either audio or visual stimuli.
