About

Rudiment

Features
Read full description

Rudiment turns practice into a game; hit-by-hit judgement, real grading, and a curriculum that actually builds your timing. Built for iPad, with a streamlined layout optimized for iPhone. Play with your fingers on the built-in pad grid, plug in MIDI hardware (MPCs, drum machines, e-kits), or use Acoustic Mode to play your real acoustic kit near the mic (BETA). Every hit gets judged in real time, Perfect, Early, Late, or Miss and scored into a D-through-S grade based on your consistency, not just raw hits. WHAT'S INSIDE - Foundations: 16 focused drills building the fundamentals from the ground up - Lessons: 16 lessons layering real technique on top of those fundamentals - Patterns: a genre-spanning pattern library across Easy, Medium, and Hard difficulty - Game Mode: a guided curriculum that only lets you advance once you're actually playing consistently, not just once - Genre Packs: 13 curated pattern collections spanning Trap, Drill, Boom Bap, Lofi, Jazz, Afrobeats, House, Jersey Club, Phonk, R&B, Reggaeton, and more - Personal Records: every pattern, lesson, and song keeps its own best score, grade, and streak PLAY YOUR WAY Rudiment adapts to how you actually play. No hardware? The on-screen pad grid works out of the box. Own an MPC, drum machine, or MIDI-capable e-kit? Rudiment learns its exact layout automatically, no manual setup, no guesswork. Prefer your real kit? Acoustic Mode listens for kick, snare, and hihat and judges you against them directly. Not happy with the built-in drum sounds? Load your own samples for any lane, swap in your own kicks, snares, and hats from your own audio library. BUILT FOR REAL PRACTICE, NOT JUST HIGH SCORES Rudiment's grading rewards consistency over time, not just a single lucky run, the same discipline a real drummer builds on a practice pad. Whether you're a finger-drummer refining your MPC chops, a producer wanting tighter programmed rhythm, or a drummer looking for a focused way to drill timing, Rudiment gives you honest, immediate feedback on every single hit. Free to start: play Foundations, Lessons, and Patterns right away, with Game Mode open through its early stops. Unlock the full curriculum and every genre pack as you're ready for more.
