About WhenRedTap
Remember racing friends on a digital watch? Red Light Reflex turns that into a set of reaction games: tap the instant the screen turns green and find out how fast your nerves really are. SEVEN MODES, UNDER A MINUTE EACH • Green Light — wait on red, tap on green. Average of 5 rounds. • Stop or Go — tap on green, hold back on red and yellow. • Bubble Pop — the whole grid lights up. Pop every light. • Lights Out — five red lights go out. Launch like an F1 driver. • Stopwatch · Quick Split — start, stop, as fast as you can. • Stopwatch · Exactly 1.00 — stop at exactly one second. The digits vanish after half a second. • Stopwatch · Tap Burst — how many taps in 5 seconds? DAILY CHALLENGE One mode a day, the same random sequence for everyone in the world, first try only. Keep your streak and see where you rank. HONEST TIMING Measured from the frame the light actually appears to the moment your finger touches down, with 120 Hz ProMotion support. Waits are truly random — no rhythm to guess — and anything under 100 ms is a false start. LEADERBOARDS AND BADGES • Game Center leaderboards plus a daily board; weekly and monthly boards in the app • 20 badges to collect • Challenge friends directly on iOS 26 • React to other players’ scores with an emoji AND MORE • Six tiers: Overclocked, Lightning, Cheetah, Sharp, Human, Sloth • Skins: classic traffic lights or a retro seven-segment LCD • Light and dark mode • Share cards for your best results Green Light, Stop or Go and the Daily Challenge are free forever. Other modes can be bought one by one, or played free for 30 minutes after watching an ad. Pro unlocks every mode and skin — including future ones — with no ads.
