New · the story of your set

Averages lie. Your set has an arc.

A single score can't tell you that you got 17% softer after midnight but stayed just as tight — or that you rush the choruses. DrumPulse reads the shape of your night, from real sets (these screenshots are a real 2h40m, 13,864-hit session):

📈

Set arc & trend

Did you fade or hold up? An early-vs-late read of strength and steadiness over the whole set — "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 tempo slope inside each song — "Tempo climbed inside 13 of 21 songs — watch the push."

⏳

Playing time

How much of the session you actually played vs. rested, and your longest unbroken run. A 2h40m set with 58% playing is a different night than 90% noodling.

🎚️

Dynamic range

How wide your touch really is — the strength gap between your ghost notes and your accents, as a ratio: 5.7× soft → loud.

What it does

A fitness record and a timing report, at once

DrumPulse listens to the motion of your snare hand, turns each strike into data, and gives you both a real workout and a coach for your time.

🏃

Saved as a real workout

Each session writes to the Health app with duration, heart rate, and active energy — so your drumming counts toward your activity rings.

🎯

Rushing / dragging feedback

A groove meter swings orange when you're ahead of the beat, blue when you're behind, with an "in the pocket" score for the whole set.

❤️

Live heart rate & calories

Your heart rate on your wrist while you play, plus calories estimated from a drumming MET value and your body weight.

🥁

Live tempo (BPM)

Your current tempo, derived in real time from the timing between your hits.

💪

Dynamics

Every hit is split into ghost / body / accent relative to your own playing, so the recap shows the light-and-shade in your set.

🎼

Per-song breakdown

In Free Play a long set is split into songs on the natural pauses, so each song gets its own tempo, timing, and dynamics rollup.

🎚️

Calibration

"Hit the pad 8 times" and DrumPulse sets detection sensitivity from your real strikes — no guess-and-check.

🕘

History & trends

Your recent sessions are kept on the watch and synced to the iPhone companion, where the bigger screen shows trends across sets.

🫀

Recovery & zones

Heart-rate recovery one minute after you stop (a fitness marker), plus time-in-zone across the set — drumming is cardio, tracked like cardio.

🔊

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.

🎯

Accent lag

Do your hard hits land later than your soft ones? A habit mean deviation hides — DrumPulse splits timing by strength tier and tells you.

⏸️

Breaks that don't cheat

Pause for water and the clock, calories, and grading all freeze. A break is a song boundary, not a hole in your stats.

Metronome	A fixed click you set the tempo for	Objective practice — each hit is graded ahead/behind a steady grid, like a timing trainer.
Free Play	Your own recent groove	Open playing — it learns your established tempo and flags when you speed up or slow down relative to yourself, no click needed.
