Reflex Trainer vs Danzu

Reflex Trainer measures your reaction time with precision, using real motion detected by your Apple Watch or iPhone. How It Works A visual stimulus flashes on your screen. React as fast as you can by throwing a punch (detected by your Apple Watch or iPhone accelerometer at 50Hz). Your reaction time is measured in milliseconds. Two Training Modes Combat Sports Mode Designed for boxing, MMA, kickboxing, and martial arts athletes. Throw a real punch when you see the flash. Your Apple Watch detects the motion, no screen tapping needed. Hold your phone in your fist as a fallback when training without a watch. General Reaction Mode A classic reaction time test for anyone. Tap the screen or move your wrist the instant you see the stimulus. Perfect for gamers, athletes, and anyone who wants to measure and improve their reflexes. Live 1v1 Duels Challenge a friend to a real-time reflex showdown. Share a code over iMessage or jump into the public lobby for a quick match. Both phones fire the same stimulus at the exact same moment, with server-authoritative timing keeping every round fair. Best of 1, 3, 5, or 10 rounds. Fastest reaction wins. Friends, Stats & History (NEW) Your Profile now has three tabs: Stats for your personal bests, History for every session you've ever run, and Friends for the people you train against. Add friends by username, get a push notification when they accept, and tap any past session to see every individual rep. Compare reaction times head to head and track your progress over time.

Ever wonder if you're actually a good dancer? Danzu tells you — with a number you can trust. Film 10–30 seconds of dancing and get a score across six axes, plus coaching feedback built from your own moves. Freestyle or choreography — no reference video to copy. WHY DANZU IS DIFFERENT Most dance apps score how well you copy a reference video. Danzu scores YOUR dancing — any song, any moves, any room. And it's honest: every axis is measured against chance, so a strong score means something real — and when a clip doesn't carry enough signal to judge, Danzu says so instead of guessing. YOUR SCORE, SIX AXES • Timing — are you locked to the beat, down to the 8th notes? • Groove — the bounce that connects your moves to the music • Sharpness — how cleanly your accents hit • Amplitude — how big and committed your movement is • Variety — the size of your movement vocabulary • Dynamics — verse-to-chorus contrast and energy shifts SEE YOURSELF THE WAY THE AI DOES Your own video plays at the top of every result with a live skeleton overlay tracking you joint by joint. Weak moments are flagged on a timeline — tap one and the video jumps right there. TEACHER-GRADE FEEDBACK Not just a number. Danzu points at the exact thing to fix — "you're about 150 ms behind the beat" or "your arms land late" — the way a teacher would, after every single video. MADE FOR YOUR STYLE Hip-Hop · Breaking · House · K-pop · Contemporary · Shuffle · Heels — plus a general mode for everything else. TRACK YOUR PROGRESS Every analysis is saved with its full feedback. Watch your scores climb week over week, find your weakest axis, and turn it into your strongest. Share your score card — with you in it. HOW IT WORKS 1.
