RudiDrum

Watch the sticks. Match the rhythm. Own the rudiment. RudiDrum turns the 40 essential drum rudiments into something you can see. Two drumsticks play the pattern above a practice pad in 3D, and every strike leaves a glowing arc behind it — so a paradiddle stops being a row of letters and becomes a shape you recognise. Then you play it back on two tap zones, and your own rhythm draws its trail right next to the reference. No kit required. No metronome app juggling. No sheet music to decode first. HOW IT WORKS 1. Watch. The sticks demonstrate the rudiment at your tempo with correct stroke heights — accents tower, taps stay low, grace notes barely leave the head. 2. Play. Tap along on two zones, one per hand. 3. See. Your trail against the reference trail, overlaid on the same timeline. Drift shows up as a gap. A swapped hand shows up in the wrong lane. SCORED PROPERLY Because you play with two hands on two separate zones, RudiDrum knows which hand played which note. So it tells you more than "you were late": • Timing precision, measured in milliseconds • Whether you rushed or dragged, and by how much • Whether one hand is limping behind the other • Exactly which notes came off the wrong hand • Notes you missed, and taps that did not belong Every pass ends with one sentence on what went wrong and one on what to do about it. TEMPO THAT MOVES WITH YOU Start slow. Switch on Ramp and the tempo climbs after two clean passes in a row, then backs off the moment it stops being clean. Your fastest clean tempo for each rudiment is the number that actually measures progress — accuracy alone can always be bought by slowing down — and that is the number the app keeps.

Practice lets you drill anything you already know, at any tempo you like. ALSO INSIDE • A metronome with an accented downbeat • Pad hits that follow the dynamics — accents loud, taps quiet, grace notes ghosted • A practice streak, a mastery count, and a tempo trend for every rudiment • Completely offline. No account, no sign-in, nothing leaves your phone. WHO IT IS FOR Drum students working through a rudiment sheet. Marching percussionists. Kit players who want their weak hand to stop being the weak hand. Anyone with a practice pad who is not sure whether their doubles are actually doubles. RudiDrum is a practice tool, not a rhythm game. No combos, no lives, no leaderboards. The reward is watching the trails come out clean and symmetrical — because that means your hands did.
