1 Second Game: Reaction Time

Reflex Test & Tap Challenge

Only for iPhone

Free

iPhone

Test your reaction time in three rounds. Can your combined total beat one second? 1 Second Game brings the tension of a racing start to a quick reflex challenge. Hold the fingerprint pad as five lights come on. When they go out, release, find the target and tap. The wait changes and the target appears in a random position. Go too early and it's a false start. EVERY TAP COUNTS • See each round's time and your three-round total. • Chase personal bests and daily, weekly and all-time Game Center leaderboards. • Unlock achievements and share a personal-best image with friends. • Choose from 20 languages, with optional music and haptic feedback. • Play rounds offline. Game Center leaderboards require sign-in and an internet connection. • Optional in-app purchases let you remove ads or support the developers through the Pit Crew. Hold steady. Lights out. Go.
