Riddiments vs Session

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.

Your offline practice room. Any song → your speed, your key, no lead vocals — everything runs on your iPhone, nothing is uploaded, and it's completely free. REMOVE VOCALS — OR KEEP ONLY THEM On-device AI splits any song into vocals and backing. Practice with a clean instrumental, or solo the vocal to study the phrasing. Works with audio files and videos. SLOW DOWN WITHOUT CHANGING PITCH 50–150% speed with clean time-stretching. Step-Up Tempo raises the speed a little every loop — the classic way to master a hard passage. CHANGE THE KEY ±12 semitones in real time. Session detects the song's key and shows you where your transposition lands. LOOP EXACTLY THE RIGHT BARS Drag precise A-B handles on the waveform, snap them to the detected beat, and save named sections (verse, chorus…) to jump between. EXPORT YOUR PRACTICE MIX Export audio — or the original video with your slowed, re-keyed, vocal-free mix, picture retimed to stay in sync. Save straight to Photos. PRIVATE BY DESIGN No account. No cloud. No upload. Your music never leaves your phone — and there's no monthly fee, no usage quota, no catch. Made by the developer of TakeCover Studio.
