Drumaio

Metronome, drum chart editing, loop practice, and full-song backing tracks — Drumaio keeps your drum practice in one offline app.

Drumaio is the all-in-one practice tool for drummers — from your very first rudiment to full-song rehearsal.

Built for students, teachers, and gigging drummers who want one app that covers the metronome, the pattern editor, the score, and the backing track — all offline, all on your phone.

— A METRONOME THAT KEEPS UP WITH YOU • Precise BPM controls, drag or tap to dial it in • Any time signature: 4/4, 3/4, 6/8, 5/4, 7/8, and more • 4-dot beat indicator shows downbeats at a glance

— EDIT GROOVES THE WAY YOU THINK • Tap cells on a step grid to build any pattern • Add or remove bars on the fly • Save up to multiple patterns side by side (A / B / C slots) • Drag-select any bars to loop the tricky part

— IMPORT & CROSS-SECTION LOOP • Import patterns shared as .zip files • Loop across A → B → C sections seamlessly • Practice transitions, not just patterns

— EVERY DETAIL OF A REAL DRUM CHART • Ghost notes, grace notes, 32nd-note pairs • Per-bar BPM override for accelerandos, ritardandos, bridges • Standard drum notation rendered in real time as you edit

— PRACTICE WITH A FULL SONG • Upload any MP3 / WAV / M4A from Files or iCloud • Fine offset slider to align downbeats • Independent volume for the song and the drums

— LANDSCAPE PRACTICE MODE • Full-screen landscape view for stand-mounted practice • Long-press the score to reveal multi-row drum charts • Built-in count-in lets you settle before bar 1 • BGM follow mode keeps the metronome locked to the track

— MAKE IT YOURS, KEEP IT SAFE • Three drum sample kits — switch in one tap • Light, dark, and custom themes • One-tap backup / restore of patterns, BGM, and settings as a single .zip • All data stays on your device — no account, no cloud, fully offline

DESIGNED FOR REAL PRACTICE • No subscriptions, no ads, no sign-up • Works fully offline once installed • Built and maintained by a dev team who actually plays drums
