Tapday: Reaction Time Test

How fast are you, really? Tapday measures your reaction time in 30 seconds and turns the number into something you can feel: your reaction age and where you stand among people your age. Then it gives you a reason to come back. Every day Tapday lines up 3 tests that take about 3 minutes in total. Finish them, keep your streak alive, and watch your trend on the graph. TESTS • Reaction time — tap the moment the screen changes color • F1 start — five lights go out, then tap • Tap speed — as many taps as you can in 10 seconds • Aim trainer — tap targets as they appear (Premium) • Stroop test — choose the ink color, not the word (Premium) • Go/No-Go — tap the green, hold on the red (Premium) • Time perception — stop at exactly 10 seconds (Premium) RESULTS THAT MEAN SOMETHING • Reaction age and an age-group percentile for reaction tests (enter your birth year) • A one-line comparison you will want to share • Personal bests and a trend graph for every test (last 7 days free, unlimited with Premium) • Sleep and caffeine tags on every result DAILY ROUTINE • 3 tests a day, about 3 minutes • Streak counter and a monthly calendar of completed days • Share your result as a clean card image PRECISE MEASUREMENT Stimulus and touch are timed on the same clock, with no animation between them.
