Plug in your e-kit via USB or switch on the microphone. The moment you hit, the note lights up: green on time, orange early or late, red when missed. An arrow shows which way you drifted.

Wait mode
Learn a hard bar one note at a time
The app stops on the next note and waits until you hit the right drum. No tempo pressure — your hands and feet learn the order first, speed comes later.
Notes played together (kick + hi-hat) are waited for together
Wrong drum flashes red, the right one turns green
When you're ready, one click back to real tempo
Dashboard & curriculum
You always know what to practise today
8 courses and 64 units across beginner, intermediate and advanced. "Today's practice" picks the etude and walks you up a tempo ladder; daily goals, streaks and badges keep you going.
Stars on every etude: 1–3 ★ as you hit the target tempos
12-week practice map and a daily goal ring
Optional email reminder on days you haven't hit your goal
Play along
Bored of the click? Play with a band
Drumless songs in each course's style: soul, funk, neo soul, hip-hop, jazz-funk, drum & bass, gospel, shuffle. The song follows your tempo without changing pitch and stays locked to the etude.
Learn slow, speed up with the same song
Voice counting in 10 languages: "1 e & a", triplets "1 & a"
Fills and crashes to end each phrase

Click, hear, save
Write your own groove by clicking a grid — the notation appears instantly, listen and save. 16ths or triplets, 1–4 bars, the whole kit from hi-hat to floor tom.
Saved etudes are practised and rated like any other

The engineering behind the sound
Built to sound real
Groove Coach behaves like an instrument, not a game. Every sound and every millisecond was tuned for that.
Sounds recorded from a real kit
94 samples recorded from an acoustic kit. Every drum has several velocity layers and alternating takes, so the same note never plays back identically twice in a row — no machine-gun effect. Ghost notes really whisper, accents ring out, and the open hi-hat stops the moment the pedal closes.
On an acoustic kit, your phone or laptop mic is enough. Real-time signal processing inside the browser listens across three frequency bands, catches sudden energy jumps within milliseconds and filters out room echo and background noise. Every stroke is measured for both timing and loudness: is the ghost really soft, is the accent strong enough?
AudioWorklet · 3-band filters · adaptive noise floor · audio never leaves your device
Millisecond-accurate timing
Every stroke is scheduled ahead on the sound card's own clock, so the moving cursor and the lit note match the moment the sound reaches your ears. Bluetooth and speaker delay are compensated, and your e-kit's latency is calibrated with one button.
Soul, funk, neo soul, hip hop, drum & bass, shuffle… 16 play-along tracks were composed with AI, then a neural network removed the drum track — you are the drummer. Change the tempo and the song speeds up or slows down without changing pitch, staying locked to the beat.
The "one e and a" count is voiced in 9 languages with neural speech models. It runs on the same clock as the metronome, so sixteenths and triplets land exactly in place.

Frequently asked
Do I need an electronic kit?
No. With an acoustic kit the microphone rates timing and dynamics, and you can use the notation, counting and play-along without any kit. The most detailed feedback (including which drum you hit) comes from a USB e-kit.
Which e-kits work?
Any kit with USB MIDI: EFNOTE, Roland, Alesis, Yamaha, Simmons… Plug it in using Chrome or Edge and the app finds it. Map unusual pads with "Learn pads" in a few hits.
How does the free trial work?
For 14 days after sign-up you get the first 3 etudes of every level and all the tools; no card needed and nothing is charged automatically. Choose a plan to unlock the full curriculum.
Do I pay for my students?
No. The teacher plan covers free accounts for up to 30 students; they don't pay anything. Music schools: get in touch.
Where are my recordings stored?
Only you and your teacher can see assignment recordings; they're deleted after 90 days. The mic only runs when you switch it on and rating never records audio. Download your data or delete your account anytime.
Can I cancel anytime?
Yes, in one click. You keep access until the end of the paid period, and in the EU you can get a full refund within 14 days of your first payment.
