Only for iPhone
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
15 modules made by a drummer: Creator, polyrhythms, rhythm reading, metric modulation, claves & more. One-time payment — no subscriptions, no ads
Your metronome doesn't train you. It just clicks.
KingMetronome is a rhythm training lab for drummers and serious musicians: polyrhythms, sight-reading, metric modulation, claves, displacement and more specialized modules. One-time payment, no subscriptions, no ads.
15 SPECIALIZED MODULES:
Metronome, Rhythm Reader, Claves, Negative Space, Timing Test, Adaptation, Amalgams, Displacement, Polyrhythms, Metric Modulation, Tap Trainer.
- Elastic Phrase — Phrases with gradually changing tempo
- Polymeter — Two time signatures playing simultaneously
- Microrhythm Masterclass by Malcolm Braff — Infinite phrasing slider between straight pulse and grooved feel
WHAT MAKES IT DIFFERENT:
◆ MICRORHYTHM MASTERCLASS — Built around Malcolm Braff's General Theory of Rhythm. The infinite zone between straight and grooved that no other app has.
◆ TIMING TEST — Find out how precise you are, down to the millisecond.
◆ NEGATIVE SPACE — The metronome disappears for 1, 2 or 4 bars. Can you hold the tempo alone?
◆ POLYRHYTHM TRAINER — 3:2, 4:3, 5:4, 7:5. Hear them, feel them, master them.
◆ AMALGAMS — Additive rhythms (4+3, 3+3+2). Hypnotic and addictive.
◆ METRIC MODULATION BUILDER — Build any tempo equivalence you can imagine.
◆ TAP TRAINER — Tap along to find your average tempo and consistency.
KEY FEATURES:
- Works 100% offline
- Premium audio samples
- Available in English, Spanish, French
- Odd meters (5/8, 7/8, 9/8, 11/8, 13/8) and Balkan presets
- Swing/Feel slider on every module
- One-time purchases. No subscriptions. No ads.
BUILT FOR:
Drummers, percussionists, guitarists, bassists, pianists, music students, teachers — anyone tired of "good enough" timing.

more NEW IN ELASTIC PHRASE
A new ring view shows how each note stretches against an even grid. The phrase is now written on a staff, and there are new sounds to choose from.
FIXED
I fixed audio export: your phrases and songs now save as WAV properly. Touch handling on notes is also better — tap to switch a note on or off, drag to stretch it, and double-tap to choose its sound without changing its state.

METRONOME
FIXED
The metronome could freeze when you left it and came back, forcing you to reopen it from the menu. The audio engine now detects a stalled clock and rebuilds itself, so you can move between modules freely.
STUDY TIME
Your practice time now goes straight to your total when you press Stop — no need to save it by hand. Each play-to-stop stretch is a complete session, and the session clock resets so you always see what you're doing right now.
COUNTDOWN TIMER
Set a target in minutes and get an alert when you reach it. It counts down only while the metronome is sounding, so leaving your phone aside doesn't eat your session.
EVEN TEMPO RAMP
Tell it where to start, where to end, and how many minutes it should take. It works out the rest and spreads the change evenly — one BPM at a time, all steps identical, landing exactly on the minute you asked for. The count-in now plays at your starting tempo, so you enter with the right reference.
DYNAMICS
The downbeat accent has its own volume, separate from manual accents. You can finally raise one without dragging the other along.
VOLUME CONTROLS
Redesigned for fingers. Tap anywhere to set the level, or use the − / + buttons for fine adjustment. No more hunting for a tiny slider handle.

Negative Space: write your own pattern as text (x-x- -x--), or hit the dice for a random one. Now opens in 2/4.
