Free ADHD focus training game online.
The ADHD Focus Trainer is built around the Go/No-Go paradigm — one of the most studied tasks in attention research. Tap quickly on green circles, but resist the urge to tap red ones. It sounds easy until your finger gets ahead of your brain.
The Go/No-Go test is the most validated measure of impulse control in cognitive psychology. People with ADHD typically score lower on it, and consistent practice has been shown to improve sustained attention and reduce impulsive responding. It's used in clinical and research settings worldwide.
