TapReaction vs One Brain

How fast are you really? TapReaction measures your reaction to the millisecond – in four game modes, on your own or in a duel against your friends. FOUR MODES • Color – A tile lights up. Tap it as fast as you can. • Numbers – Find the number shown on the board. • Time – Tap as many lit tiles as possible in 30 seconds. • Traffic Light – The classic reaction test: wait for green, then tap. Too early is a false start! FAIRLY MEASURED TapReaction responds the moment you touch, not when you lift your finger. Misses add a time penalty – so results stay honest and comparable. TWO-PLAYER DUEL Play together on one device: the same tile lights up for both of you – whoever taps first wins the round. Side by side or face to face, on iPhone, iPad and iPhone Duo. MADE FOR IPHONE DUO Fold your iPhone Duo like a book – each half belongs to one player. In tabletop pose you see your target at the top and tap on a stable surface below. Nothing important ever lands in the fold. Close it, and simply keep playing on the outer display. DAILY CHALLENGE A new challenge every day – the same for everyone worldwide. Compare yourself on the daily Game Center leaderboard and build your streak. GAME CENTER Leaderboards, achievements and challenges. Rankings use the standard setup, so everyone plays under the same conditions. YOUR STATISTICS Best times, averages, accuracy and highscores for every setup. With Pro, charts show how your reaction time improves. LEVELS & DESIGNS Every round earns experience – new bests and the Daily Challenge give bonus XP. Rise from Rookie to Legend and unlock new tile designs along the way: Ocean, Candy, Forest, Sunset. Add the Neon, Retro and Black & White design packs if you like – purely cosmetic, scoring stays the same for everyone. FOR EVERYONE • Boards from 16 to 56 tiles, games from 10 to 200 taps • Symbols on colored tiles for color vision deficiency • VoiceOver, Dynamic Type, Dark Mode • Separate sound and haptics settings FREE AND FAIR No ads, no tracking, no subscription. All game modes are free. TapReaction Pro (one-time purchase, Family Sharing) unlocks the duel, statistics charts and the Gold design. Design packs are available individually, and if you like, you can support development with a tip. Your highscores from TapReaction 2 are kept when you update.

One Brain is inspired by the Stroop effect, a famous psychological test that measures how well you handle conflicting information. For example, it's harder to name the color of a word when the word itself spells a different color. This game challenges your whole brain as you fight to process the mixed signals and make the right call before time runs out. Game modes: • Colors: Does the word match the color it's written in? • Arrows: Is the arrow actually pointing the way it says it is? • Numbers: Is the math equation true or false? • Words: Which word matches the definition? How high can you score under pressure?
