How fast are you, really? No ads, no fluff: just you, the clock and a global leaderboard. Train your reflexes, beat your friends, play offline. Think you've got fast hands? Red Reaction puts a number on it. Red Reaction is a no-nonsense reaction-speed trainer built for competitive and FPS players – and for anyone who just wants to know how quick they really are. Four buttons. One split second. Hit the right one before the moment's gone. HOW IT WORKS Watch the grid. React. Every tap is measured, every round is scored, and every millisecond counts. ONE MODE. PURE SKILL. No menus to dig through, no modes to pick. Every run is the same test for everyone, so every score is a fair fight. Start a run, set a time, try to beat it. COMPETE GLOBALLY – AND WITH YOUR CREW Put your best score on the global leaderboard and see where you stand against players around the world. Then create custom leaderboards to go head-to-head with your friends, squad or clan. BUILT FOR WARM-UPS Use Red Reaction as a quick pre-match warm-up before ranked, or as a daily reflex check to track your progress over time. PLAYS OFFLINE No connection? No problem. Train anywhere – on the train, between matches, or waiting in queue. - Fast rounds you can play in seconds - Personal high scores saved on your device - Clean, distraction-free design - Made by a solo indie developer at Zeroskills Games How fast are you?

You can connect your account with apple account to be able to reuse the stats if you change phones or something. There is odds and ends updated. New countdown feature and music :) Enjoyy.
