About BrainGym
One developer. One thesis. No claims that the cognitive-psychology literature does not back.
Why this exists
Most "brain training" products got popular by promising to make you smarter. The cognitive-science literature does not actually support that, and the FTC has historically pushed back when companies overclaim. We built BrainGym to see what an honest version of the category looks like - one where the difficulty is the product, the research is on the page, and the goal is "you got better at sustaining attention" rather than "you increased your IQ".
Who built it
BrainGym is built and maintained by a single developer. The puzzles, stories, and Treadmill sessions are hand-authored. The grading bank for typed reasoning (when that feature is available) is hand-written, item by item. Nothing here is mass-produced or AI-spammed; if a piece of content cannot pass the "could you Google it?" filter, it gets cut before shipping.
What we do not promise
- - We do not promise IQ gains. The evidence does not support it.
- - We do not promise transfer to unrelated life tasks. Far transfer is contested.
- - We do not promise BrainGym is the right tool for everyone. The comparison page tells you when to pick something else.
What we do promise
- - Honest copy. If the research changes, the page changes.
- - The product stays free at launch. If that ever changes, you will know first.
- - Every puzzle ships with a real explanation of the answer, not just "correct" / "incorrect".
- - We do not sell user data. Cognitive metrics you generate are yours.
