Beatkeep

Beatkeep is a tap-tempo meter that grades your timing. Most BPM tap apps just compute an average. Beatkeep also tells you, in real time, how consistent your taps are — a single "Beatkeep" percentage from 0 to 100, plus a small bar chart of your last eight intervals. WHO IT'S FOR • Musicians warming up to a click • Drummers checking groove consistency • DJs counting cues by ear • Dancers locking in a tempo • Anyone training a sense of time HOW IT WORKS • Tap anywhere on the screen • After two taps you get a live BPM readout • After three taps Beatkeep starts scoring your consistency • Pause for three seconds and the next tap starts a fresh measurement WHAT'S INSIDE • Real-time BPM display • Stability score (0–100%) based on the standard deviation of your intervals • Visual bar chart of your last eight tap intervals • Color-coded feedback: green when you're locked in, orange when drifting, red when erratic • Light haptic feedback on every tap NO ACCOUNTS. NO ADS. NO TRACKING. Beatkeep is a single-screen utility. It doesn't collect data, doesn't talk to a server, and doesn't ask for any permissions. The whole app fits in your pocket and works offline forever.
