About

Reaction Time & Reflex Speed

Features
Read full description

Reaction Time is a fast, focused arcade challenge built around one goal: tap with precision. Three modes, three ways to test yourself: • Zap Reactor: wait for the cue and react under a shrinking time limit. • Neon Rail: stop the beam inside the zone as it speeds up and narrows. • Chrono Snap: hit the stop as close to 2.000s as you can. Progress through levels, survive three strikes, and chase tighter windows. Track your best runs, highest levels, and tightest locks in detailed stats. Crisp visuals, haptics, and sound controls keep the experience punchy and clean. No accounts, no clutter — just quick sessions that sharpen your timing.

Mind Gym puts 14 short brain tests in one app. Check your reaction time in milliseconds, see how much your memory can hold, beat the Chimp Test, race the clock in math and typing, and climb the weekly and all-time top 50 in every game. Each game takes about a minute, so it fits in any break. SPEED - Reaction Time: wait for green, then tap. Three taps, one average in milliseconds. - Aim Trainer: hit 30 targets that get smaller as you go. - Typing Speed: type as fast as you can for 30 seconds and see your words per minute. - Math Sprint: answer as many sums as you can in 60 seconds. They get harder as you score. MEMORY - Number Recall: a number shows, then hides. Type it back. One more digit each round. - Letter Recall: the same test with letters. - Visual Recall: squares light up on a grid. Tap the ones you saw. - Sequence Recall: watch the pattern, then repeat it in order. - Chimp Test: tap 1 and the numbers turn blank. Tap the rest in order from memory. - Verbal Recall: words show one at a time. Seen it before, or new? FOCUS - Color Confusion: the word says GREEN but the ink is red. Don't let it fool you. - Not Not: "not left" means anything but left. Think fast before time runs out. - N-Puzzle: slide the tiles of the classic 15 puzzle into order and beat your best time. - Tower of Hanoi: move the whole tower to another peg, one disc at a time, in the fewest moves. WORLD RANKS Every game has a weekly board that starts fresh every Monday, plus an all-time top 50. See your rank right after each game and your rank badges on the home screen. Sign in with Apple or Google to put your name on the board. Playing as a guest? You still see where you would rank. REMINDERS Smart reminders bring you back for a quick brain workout, and tell you when the weekly board is about to close. Pick your own time, or turn them off in Profile. YOUR BEST, SAVED Your best score in every game is saved on your profile, and signing in keeps it safe on every device. WHY PEOPLE LIKE IT - Short games, about a minute each - Play as a guest, no sign-up needed - Games work offline; only the ranks need internet - Clean, dark design that is easy on the eyes - Remove ads for good with one small purchase QUESTIONS What is a good reaction time? Most people score between 250 and 350 ms. Under 250 ms is fast, and under 200 ms is great. How many digits can most people remember? About 7. Number Recall adds a digit each round, so you find your own limit. Is it free? Yes. All 14 games and the ranks are free, with ads. STORE (OPTIONAL) In most games, if you lose you can keep going once per game by watching a short ad or using a life. In N-Puzzle, a life or an ad gets you 3 hints. Lives can be earned free by watching ads, or bought 25 or 60 at a time; they are added to your account and never run out. No Ads removes every banner and full-screen ad for good. All are one-time purchases: nothing renews, and everything comes back on any device signed in to the same account. Sign-in is needed to buy, so purchases stay tied to your account.
