Reaction time test and reflex trainer: measure your reaction speed in milliseconds, compare it with the ~273 ms public median, and train to get faster. Free to start. How fast are you, really? Reflexa gives you the number in five seconds — and a plan to beat it. ā–ø TAKE THE REACTION TIME TEST The classic green-flash test, done right on your phone. Wait for green, tap. Your result appears instantly in milliseconds with your tier — Lightning, Nice Reflex, Average or Room to Grow — and where you land against the median of millions of public reaction tests. Timing runs on your device, so there is no mouse or browser latency inflating your score. ā–ø WHAT IS A GOOD REACTION TIME? • Under 200 ms — lightning: the range of competitive gamers and athletes • 200–250 ms — a genuinely fast reflex • ~273 ms — the public median most people land around • 300 ms and above — plenty of headroom, and the fastest gains Reaction time peaks in your twenties and slows with age, fatigue and lack of sleep. It also improves with practice. ā–ø 60 REFLEX CHALLENGES, 15 MECHANICS Reaction speed is not one skill. Reflexa trains every kind: • Classic — pure visual reaction time • Phantom — the target vanishes, trust your instinct • Stroop test — your eyes say one thing, the word another • Peripheral — catch what appears at the edge of your vision • Pursuit, Catch, Echo, Glimpse, Heartbeat, Eclipse, Lightning, Crossfire, Duet, Trace, Pendulum Each mechanic has four difficulty tiers: Easy, Normal, Hard, Expert. ā–ø ELO RANKING, LIKE CHESS A real skill rating that moves with every run. Six ranks: Bronze, Silver, Gold, Platinum, Diamond, Legend. Beat your level and gain points, slip and lose them — every tap means something. ā–ø DAILY CHALLENGE & WEEKLY TOURNAMENT • A fresh daily challenge with streak and points • Weekly tournament for the top-score race • Game Center leaderboards: your country and the world ā–ø SMART TRAINING & PROGRESS • Personal next target: āˆ’X ms to your next tier • Sequence mode: 5-round sessions for consistency • Full history, ELO trends and session analytics • AI Coach: personalized insights on Apple Intelligence devices, generated on your iPhone • Share cards to post your rank and best time ā–ø APPLE WATCH • Train from your wrist, no phone needed • Live heart rate during the round • Three Watch-optimized challenges, synced with iPhone ā–ø WHO IS REFLEXA FOR? • Gamers who want faster hand-eye coordination for FPS, fighting and rhythm games • Athletes and drivers who need to react first when it matters • Anyone who wants to stay mentally sharp with a daily brain game • Anyone curious about their own reflex test score ā–ø FREQUENTLY ASKED Can reaction time be trained? Yes. Short, consistent practice measurably shortens it; Reflexa keeps your baseline and every session so the gain is visible, not imagined. Is a phone test accurate? Reflexa measures on-device with the same method every time, so your results are consistent and comparable day after day. Is it free? The reaction test, Easy challenges, the daily run and your history are free. Pro unlocks the rest. Free to download. Your first test takes five seconds. ——— REFLEXA PRO All 60 challenges, Normal to Expert, weekly tournament, full history, AI Coach, themes and iCloud sync. Free trial available, cancel anytime.

About

Reflex

Read full description

Reflex is a reaction trainer. Tap to arm, wait for green, hit it. Then see how your thumb compares with the fastest it has ever been. NINE DRILLS, EACH WITH ITS OWN TOP TEN • Reaction — hit green as fast as you can. One reaction, in milliseconds. • Go / No-Go — tap green, hold still on red. A tap on red ends the run. • Precision stop — a 3-2-1 count, then stop the clock on exactly 1.000 s. The digits hide after 0.3 s. • Aim trainer — twenty targets, one at a time, anywhere on the screen. • Choice reaction — two pads go amber, one turns green. Tap that one. • Tap speed — as many taps as you can in five seconds. • Sequence memory — nine tiles light up in a growing, quickening sequence. Repeat it. • Math sprint — ten quick sums, four answers each. Pick +, āˆ’, Ɨ, Ć· or a mix. • Number hunt — a 6Ɨ6 grid of numbers. Tap them by the rule: up, down, evens or odds. IT TALKS BACK Miss your personal best and the app has opinions. Mostly ragebait, occasionally encouragement, and it gets sharper the longer the cold streak runs. False starts, taps on red and wrong pads get their own lines. Mute it in Settings if you would rather suffer in silence. EVERY BEST, KEPT The ten best runs of every drill stay on your phone, with podium medals, the top-ten average and a Bests tab you can filter by drill and mode. Each drill knows whether lower or higher is better, so records work for times and counts alike. BRAG WITH ONE TAP Any run becomes a score card in the app's own style, painted in whatever theme you are using and tagged with your username, ready for the share sheet. OFFLINE BY DESIGN No accounts, no network, no leaderboard, no ads, no tracking. Your scores never leave the phone. ALSO IN THE BOX • Light and dark themes that follow your system setting, with a manual override. • Haptics on arm, hit, new record and false start. • A daily brain-boost tip on the home screen: sleep, hydration, posture, timing. • A drill of the day and a jump-back-in card for the last drill you played. • A thirty-second tour the first time you open it. Thirty seconds to learn, a lifetime to master. Hit green.
