How fast are your reflexes? Find out in 30 seconds, then train them a little every day. Reflex is a reaction time test and reflex training app with 8 ways to measure yourself: reaction time, decision making, impulse control, tap speed, memory span and more. 8 WAYS TO TEST YOURSELF Simple Reaction: tap when the screen turns green. The classic reaction time test, in milliseconds. Choice Reaction: tap the matching direction. Measures how fast you decide, not just how fast you react. Go / No-Go: tap green, resist red. An impulse-control test. Audio Reaction: tap when you hear the beep. Most people hear faster than they see. Sequence Memory: repeat a growing pattern. Trains working memory. Tap Speed: tap as fast as you can. A CPS test (taps per second). Color Match: same colour or different? Visual processing speed. Peripheral Vision: spot the dot at the edge while you look at the centre. Visual tests are timed from the frame that shows the signal. In Simple Reaction a tap before green counts as too soon, so the round starts over and your time stays fair. A REASON TO COME BACK - Daily challenge: a different test every day, a 5-week calendar and your streak - Streak freezes cover a missed day (hold up to 2) - Training programs: Daily warm-up and Focus, a day at a time - Your weekly Reflex score from 0 to 1000, built from your best in each test - An optional daily reminder, only if you switch it on SEE YOUR PROGRESS - Trends for every test over 7, 30 and 90 days, and how much faster you are than last month - Personal bests for all eight tests, with a round-by-round breakdown of every result - An estimated percentile: roughly where your time sits against typical human reaction times - A new-best screen when you beat your record, and achievements to collect - A share card, square or story, with only the test and your time: no name, age or date MAKE IT YOURS - Test skins: Classic and High contrast for everyone, plus Arcade, Minimal and Neon - Light and dark themes - A two-column layout on tablets - In English, German, Spanish, French, Japanese, Korean and Portuguese WHO IT IS FOR Esports players warming up. Athletes working on response time. Drivers curious how quickly they respond. Anyone who has wondered how fast their brain really is.

Verdict
The clearest difference is in-app purchases: GammaLab at none against Reaction Time Test's 1. Reaction Time Test's advantage is iOS requirement (15.0 vs 17.5). On price, ads and device support there is nothing between them.
