Riddiments
Read full descriptionHide full description
Riddiments is a rhythm instrument for your pocket — a practice tool with the precision of a metronome and the expressiveness of a drum machine. Most metronomes give you one click. Riddiments gives you up to four independent rhythmic voices, each with its own time signature, sound, and feel — all locked to a single tempo. Different time signatures don't drift apart; they interlock into polyrhythm. It's the difference between counting along and actually hearing how the parts fit together. SEE THE BEAT, NOT JUST HEAR IT Four visualizations, one tap to switch between them: • Circular — a beat wheel with a playhead sweeping the ring. The signature view. • Waterfall — notes rise toward a NOW line, so you can read what's coming. • Timeline — every voice as gems on one lattice. Tap to edit, even while playing. • Notation — real single-line percussion notation with sticking letters, accents, flams, and drags. STICKINGS YOU CAN TRUST The built-in library covers the PAS International Drum Rudiments plus hybrid rudiments, rolls, grooves, and ostinato exercises — every sticking verified against published sources. Flams and drags play as true grace notes, on the correct hand. BUILD REAL TECHNIQUE • Practice mode: timed sessions, count-in, gap click, and automatic tempo progression to push your speed up gradually. • Tempo Lock, lead-hand flipping, and Alternate Lead each bar. • 18 built-in percussion voices — snare, kick, hi-hats, toms, claves, and more. • Per-lane swing, volume, and mute. Every control is live — changes land instantly, without stopping. MADE TO LIVE ON A STAND Every control works while you play. Tempo, transport, session time, and mute state stay readable from drumstick distance. Light and dark appearance. Save your own patterns, and your last session is always waiting when you reopen the app. Designed in the spirit of good tools: useful, honest, and quiet until you need it. Universal — one app for iPhone, iPad, and Mac.

Record a few seconds of anything — your voice, a clap, a passing train — and let the app pull it apart in time. What about phase? is a pocket instrument for process music: it loops your recording in two channels and lets them drift out of sync, so simple sounds grow into shifting, hypnotic patterns. Inspired by the tape-phasing experiments of 1960s minimalism, it makes the process itself audible — you set it in motion, then listen as it unfolds. TEN PROCESSES • Phasing — two copies of your loop, one drifting a few cents faster; hear them separate into echo, then canon • Gradual process — a ramp that grows louder and sweeps across the stereo field • Tape loop multiplication — your loop fanned into a detuned chorus • Rhythmic construction — a rhythm assembled hit by hit • Pattern substitution — beats replaced one at a time: silence, octaves, fifths • Resultant patterns — two interlocking rhythms revealing a third • Clapping Music — a pattern rotating against its fixed copy • Pulse / drone — a pulse grid over a deep foundation • Canon — staggered voices entering one after another • Speech melody — a syllable pulsed in speech rhythm and dynamics THE WHEEL A radial display shows what the process is doing: your loop's waveform — or the process's own pattern — wrapped around a circle, left channel in coral, right in cyan, a comet sweeping the playhead. In Phasing you can watch the two rings physically drift apart. Volume and pitch views included, with on-device pitch detection. MADE FOR EXPLORING • Ten built-in demo takes, one per process, playable from the very first launch • Every take saves with its process and settings; rename, share as WAV, revert • Takes named after where you record them (optional, location used only while in the app) • Live controls: drift in cents, process amount, tempo, sample offset • No account, no ads, no analytics — recordings never leave your device unless you share them Record something small. Let it become something long.

Verdict
The clearest difference is in-app purchases: Riddiments at none against What About Phase?'s 1. What About Phase?'s advantage is update cadence (daily vs every 2 months) and iOS requirement (15.0 vs 17.0). On price, ads and device support there is nothing between them.
