What is ReflexJet?

ReflexJet is a brain benchmark app with 12 cognitive tests that measure your reaction time, memory, speed, and cognition. Get a composite Brain Score (0-100), track your progress with tier rankings (Elite, Fast, Average, Slow), and compete on weekly leaderboards.

What are the 12 brain tests?

Reaction Time, Sequence Memory, Number Memory, Aim Trainer, Stroop Test, Chimp Test, Typing Speed, Visual Memory, Verbal Memory, Go/No-Go, Trail Making, and Speed Match. Each test targets a different cognitive skill.

Is ReflexJet free to play?

Yes. ReflexJet is completely free to download and play. All 12 brain tests, daily challenges, multiplayer, and achievements are available at no cost.

How is Brain Score calculated?

Your Brain Score (0-100) is a composite of your best scores across all tests you have played. Each test is normalized to a 0-1 range and averaged. Missing tests are excluded, not counted as zero. The more tests you play, the more accurate your Brain Score becomes.

What are the tier rankings?

Based on your Brain Score: Elite (85+), Fast (55+), Average (25+), and Slow (below 25). Each test also has its own tier based on your performance. Tiers help you understand where you stand compared to average human benchmarks.

How does multiplayer work?

Create a private room with a 6-digit code and share it with a friend. Both players play 6 randomly selected mini brain tests simultaneously. Scores are compared at the end. You can rematch with new tests.

How does the daily challenge work?

Every day, all players worldwide get the same brain test to complete. Play it to build your daily streak. The test type is determined by a SHA-256 hash of the date, so everyone gets the same challenge.

Does ReflexJet work offline?

Yes. All 12 brain tests work perfectly offline. An internet connection is only needed for the leaderboard, multiplayer, and syncing your stats.
