What is BrainGame?
BrainGame is an Android brain games app for people who want to practice reaction speed, memory, and judgment for a few minutes a day. It brings 19 short mini-games together, including a reaction time test, the chimp test, the Stroop test, and N-Back, and its daily training picks 3 games for you so you can build a streak. Every game is scored from 0 to 100 so you can compare across games. You play right away without an account, and your records are stored only on your device.
How fast are you, in ms?
Reaction time is the gap between the screen changing and your finger touching it. One try gives you a feel for it, but measuring the same way every day is what shows your real record.
273ms
Median result among users of the online Human Benchmark reaction test (average 284ms). It includes device and browser delay.[1]
231ms
Average visual simple reaction time in a study of 1,469 adults (213ms after correcting for hardware delay).[2]
3 games

These figures come from other services and studies and can't be compared directly with BrainGame scores. Sources are in the footer.
Mini reaction time test
Uses the same scoring rule as the app's Simple Reaction game. When the red screen turns green, tap right away. After 5 tries, your score is based on the median (the app uses 7 tries).
1. Test yourself
Tapping during the wait (red, ■) is a false start. After 3 false starts, the test starts over. On a keyboard, press Space.
2. Score from ms
Take the test or enter a time in ms to see your score here.
