REFLEX RIVALS
A mobile game that measures your reaction time to the millisecond across 14 reflex mini-games, pits you against your friends and the whole world, and tells you exactly how fast you are. Free.
REFLEX RIVALS is a product by Bierzo Labs. It turns an invisible skill —your reflexes— into a number you can see, improve and compare. In about 30 seconds you learn your exact reaction time in milliseconds: not a feeling, but a real, repeatable, comparable result.
Everyone thinks they have great reflexes. REFLEX RIVALS lets the scoreboard settle the argument —challenge a friend to the same test, climb a world ranking spanning 60+ countries, and train with the kind of stats that tell you exactly where you fail and how to improve. Free, no ads.
Not just another game. It's your personal record.
Each of the 14 mini-games is built around a specific function —reaction time, working memory, impulse inhibition, visual discrimination, fine motor control— and logs every tap to the millisecond, with its exact position. There is no measuring at random: when you win a challenge, you really won it.
"From zero to challenging in a minute: install, sign in, pick a mode and discover how fast you really are."
Sign in with Google or Apple, pick a mode, and play. Send a challenge to your friends, check the rankings, and come back for more —the phrase "one more" never ends.

Curved Path
Unpredictable curves that get longer and faster each time.
Saltus
Teleport
The dot can jump position without warning. Don't rush.
