Reflex: Reaction Trainer
Reaction time & focus drills
Free · Designed for iPad. Not verified for macOS.
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 +, −, ×, ÷ or a mix.
• Number hunt — a 6×6 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.
