Riddiments - Drum Practice

Polyrhythm metronome & trainer

Layered rhythm

Build up to four independent rhythmic lines, each with its own time signature, sound, swing, and volume — all locked to a single tempo. Different meters don't drift apart; they interlock. It's the difference between counting a polyrhythm and actually hearing how it sits.

Four ways to see the beat

Every rhythm renders four ways, and you switch between them instantly:

• Circular — a beat wheel with a playhead sweeping the ring. The signature view.

• Waterfall — notes rise toward a NOW line, so you read what's coming.

• Timeline — every voice as gems on one lattice; tap to edit, even while playing.

• Notation — real percussion notation with sticking letters, accents, flams, and drags.

Check your subdivision, read ahead, or zoom out to the whole bar — the right view is always a tap away.

Practice tools

Timed sessions, count-in, gap click, and automatic tempo progression. Tempo Lock, lead-hand flipping, and Alternate Lead each bar. Save your own patterns — your last session is always waiting.

Stickings you can trust

The built-in library covers the PAS International Drum Rudiments plus hybrids, rolls, grooves, and ostinato exercises — every sticking verified against published sources. Flams and drags play as true grace notes, on the correct hand.

Riddiments is free for iPhone, iPad, and Mac.
