How fast are your reflexes? Find out in 30 seconds. Reflex is a reaction time test and brain training app with 8 ways to measure your speed — reaction time, tap speed, memory span, hand-eye coordination and more. Take a reaction time test, beat your personal best, and watch your reflexes sharpen week by week. 8 WAYS TO TEST YOURSELF Simple Reaction — Tap when the screen turns green. The classic reaction time test — pure visual reaction speed in milliseconds. Choice Reaction — Tap the matching direction. Measures decision speed, not just reaction speed. Go / No-Go — Tap green, resist red. A real impulse-control test. Audio Reaction — Tap when you hear the beep. Tests auditory reaction time, which is usually faster than visual. Sequence Memory — Repeat a growing pattern. Trains working memory. Tap Speed — Tap as fast as you can. A CPS test (clicks per second) for your fastest finger. Color Match — Same colour or different? Tests visual processing speed. Peripheral Vision — Spot the dot at the edge while looking at the centre. Maps your visual field. TRACK EVERY RESULT - Personal best for every mode, with a trend chart so you can see your reaction time improving - Percentile ranking — find out where your reflexes sit compared to everyone else - Consistency and accuracy scores, not just your fastest single attempt - Round-by-round breakdown of every test - Separate history for every skill — reaction time, tap speed, memory span and hand-eye coordination are tracked independently - Daily streaks to keep your brain training habit going - Shareable result cards to challenge a friend WHO IT IS FOR Esports players training reflexes. Athletes improving response time. Drivers curious about their reaction speed. Students of cognitive science. Anyone who has ever wondered how fast their brain really is. Reflex works as a daily brain training habit too: a couple of minutes a day on tap speed, memory span and hand-eye coordination is enough to see your reaction time trend downwards. YOUR DATA Every result is stored on your device — there is no account and no cloud sync. No sign-up, no email, no personal profile. Reflex is free and supported by ads, so it needs an internet connection to show them. Ads are never shown during a test, and you can watch one short video to hide them for 30 minutes. Ads are non-personalised: Reflex does not track you across apps or websites. Download Reflex and find out how fast you really are.

InForm Motion Analysis

Features
Read full description

InForm is built around the way we actually train. - Film yourself, load a video from your phone, or use the integration with YouTube to capture the motion you want to study. - Quickly loop, slow down, and zoom in to highlight the exact sequence you are training. - Easily draw, annotate and measure angles. - Take notes and record your analysis and feedback directly in the app - Save, share, and track progress. As a dancer, weight lifter, rock climber, and dance teacher, I was always looking for ways to study movement. I always wanted a simple yet powerful video analysis tool that worked with how I trained and taught, but could never find the right one. So I decided to build InForm Motion Analysis. I believe that quality resources should be available to everyone who loves motion, regardless of finances. Therefore, InForm uses a donation-based model, which means it is FREE FOR ALL TO USE! No monthly subscriptions, no ads, no features hidden behind paywalls. All that I ask is that if you find InForm helpful, then please consider donating to support continued development and maintenance. A few features that make InForm especially powerful: - You can put a YouTube clip in one panel and your own video in the other to quickly master a sequence. - Easily compare before and after videos to see check progress, or use the project folders feature to track progress from one session to the next. - Write or record notes, or film a full coaching analysis in the app - Quickly save and share edited videos.
