Reaction Time & Chimp Test

Measure your reaction time, test your reflex speed and visual memory, and solve quick pattern logic puzzles in short sessions that work offline.

Reaction Time & Chimp Test gives you a 3 minute profile across reaction, memory and logic, plus focused tests when you only want one. Results use the median of several signals, false starts are detected and replayed, and everything stays on your phone.

REACTION TIME TEST
Wait for one of 6 signals, then tap as soon as it appears. A false start is shown right away and the signal is replayed, so it never counts. Your result is the median, not one lucky tap.

RACE START REFLEX TEST (F1 START LIGHTS)
Five red lights come on one by one. When they all go out, tap as fast as you can. Tapping while a light is still on is a false start.

SOUND REACTION TEST
No visual cue: tap as soon as you hear the beep.

VISUAL MEMORY AND SEQUENCE MEMORY TEST
Watch tiles light up, then repeat the sequence. It grows each time you get it right, and your score is the longest sequence you repeated.

PATTERN LOGIC TEST (MISSING SHAPE PUZZLE)
Solve 12 matrix reasoning puzzles and pick the missing shape. Questions change with every session.

DAILY CHALLENGE AND BADGES
Play one daily challenge, the same for everyone each day, and keep a streak of consecutive days with an optional reminder. Unlock 12 badges for your first records, your fastest times and your streaks.

TWO PLAYER REACTION DUEL (REFLEX DUEL)
Challenge someone on the same phone: two players face each other and the fastest correct tap wins the round. Three more duel modes: Trap (tap on green, never on red), Sound and Race start. Available with Pro or as a separate one-time duel pack.

PROGRESS AND REACTION TIME TRACKER
Your local history shows your records, a progress chart and your 7-day average. Share a result card when you want to compare with friends.

ONE PRO TEST EACH DAY
Each day, one Pro test of your choice is open to try. Once it is used, you can watch a short optional video ad, when one is available, to open another Pro test for the rest of the day.

CHIMP TEST (NUMBER ORDER MEMORY) - PRO
Watch numbers appear, then tap them in order after they disappear. Your score is the longest sequence you got right.

STROOP TEST AND COLOR WORD TEST - PRO
Name the ink color, not the written word.

GO/NO-GO REACTION TEST - PRO
Tap on green, never on red.

NUMBER MEMORY TEST - PRO
Hold a growing number sequence in mind after it disappears.

VIBRATION REACTION TEST - PRO
No visual or audio cue: tap as soon as you feel the vibration.

MORE WITH PRO
Pro adds full reaction time history, 30-day averages, the time of day you react fastest and every duel mode. Pro removes ads. Available as a one-time lifetime purchase, a monthly subscription with a 7-day trial, a weekly subscription or a 24-hour pass.

OFFLINE AND PRIVATE
Tests work without an internet connection; ads and purchases need one. No account is required and your results stay on your device.
