DrumPulse: Drum Timing Coach

About

Turn your drumming into a workout — and your Apple Watch into a timing coach. DrumPulse listens to the motion of your snare hand, turns every strike into data, and gives you two things at once: a real fitness record and an honest report on your time. No extra gear, no mics — just your watch. ARE YOU RUSHING OR DRAGGING? A live groove meter swings as you play: orange when you push ahead of the beat, blue when you fall behind. At the end of each set you get an "in the pocket" score and a clear breakdown of how many hits landed early, on time, and late. TWO WAYS TO PRACTICE • Metronome — set a tempo and every hit is graded against a steady click, like a timing trainer. • Free Play — no click needed. DrumPulse learns your own groove and flags when you speed up or slow down relative to yourself. THE STORY OF YOUR SET Averages lie — your set has an arc. DrumPulse reads the shape of the whole night: • Set-arc trend — did you fade or hold up? "Hit strength held steady; timing tightened (±28 → ±25 ms)." • In-song tempo drift — the per-song average hides a climb from 105 to 115. DrumPulse measures the slope inside each song: "Tempo climbed inside 13 of 21 songs — watch the push." • Playing time — how much of the set you actually played, and your longest unbroken run. • Dynamic range — the strength gap between your ghost notes and accents, as a ratio (5.7× soft to loud). • Accent lag — do your hard hits land later than your soft ones? A habit mean deviation hides. DRUMMING IS CARDIO Every session is saved to Apple Health as a workout, with duration, heart rate, and active energy — your practice adds to your activity rings. Beyond the basics: • Heart-rate recovery one minute after you stop — a real fitness marker. • Time-in-zone across the whole set. • Loudness (average and peak dB) from the watch's own hearing sensors, with a warning when a set runs loud enough, long enough, to matter. KNOW YOUR PLAYING • Live tempo (BPM) from the timing between your hits. • Dynamics — every hit sorted into ghost, body, and accent relative to your own touch. • Per-song breakdown — a long set splits into songs on the natural pauses, each with its own tempo, timing, and dynamics. • Calibration — tap eight times and DrumPulse sets its sensitivity from your real strikes. • Honest pauses — take a water break and the clock, calories, and grading all freeze. ON YOUR PHONE, TOO The DrumPulse iPhone companion pulls your sessions off the watch so you can review them on a bigger screen — trends across sets, personal bests, and the full detail of any session. Weight and intensity sync from the phone, so calories stay right. PRIVATE BY DESIGN No accounts. No tracking. No analytics. No servers. Your motion and heart-rate data are used on your device only and never leave it; sessions sync solely between your own watch and iPhone over Apple's encrypted connection. Built by a gigging drummer, for drummers. Strap on your watch, hit play, and find your pocket. Note: Apple Health has no "drumming" workout type, so sessions appear as Other (branded Drumming) in the Fitness app.
