Tap out the tempo of a song from memory. See how far off you were. That "wait, I was how wrong?" moment is the whole game — for casual listeners and musicians who should know better. Challenge your friends and show off your dead-on beat memory.
How It Works
A curated track appears — title, artist, year. Do you know the tempo? You might think you do...
Tap the drum in rhythm. A drum loop follows your beat. Adjust the beat until it feels right.
See and hear your BPM vs. the actual BPM, side by side. A score, a rating, and a roast you probably deserve.
Challenge Mode - Play against your friends
Pick 5 or 10. Send via iMessage or to your in-app friends. Up to 8 friends get to try the exact same set within 48 hours — it's a fair fight: the same songs, in the same order.
The leaderboard updates as people finish, but song titles stay hidden from each player until they complete their round. Nobody gets to look up the BPM in advance.
You'll find out very quickly who actually has the rhythm in your friend group.
What Makes It Different
No number is ever shown while you're tapping. Live feedback keeps you grounded without spoiling the reveal. The surprise is the point.
Tapped at 75 BPM for a 150 BPM song? That's a valid musical interpretation. Scoring accounts for it — your ear isn't wrong, just groovy.
From "Nailed It" to "Way Off," each tier has roast copy tuned to your result. Playful, never mean, not instructional. Just accurate.
Tap "I Don't Know It" and hear a preview. No penalty, no broken streak. It's a game, not a test.
