Practice Studio

A sample-accurate metronome, a sub-cent tuner, a play-along studio and a practice journal — in one app.

Practice Studio is a complete practice room for musicians: a rock-solid metronome, a sub-cent tuner, a play-along and recording studio, and a journal that remembers every session. One app, built by a working guitar teacher.

THE METRONOME A native audio engine schedules every click on an absolute sample timeline, so it never drifts and never wobbles. • Any time signature — pick a preset or type your own • Subdivisions from eighths to sixteenth triplets, drawn as real engraved notes • Swing, from dead straight to fully shuffled • Four-level accents you edit as a histogram • Drum grooves — rock, funk, blues, swing, dance — for when a bare click isn't enough • A tempo trainer that steps or ramps you up, bar by bar • Practice timer, tap tempo, and a spoken count-in that stays in time even at fast tempos

THE TUNER • Sub-cent accuracy from real pitch detection, not a rough estimate • A strobe that behaves like a real strobe tuner, plus a graduated LED meter • Adjustable reference pitch, and an instrument mode for a clean plugged-in signal

PLAY ALONG AND RECORD • Import any audio or video file, or open one straight from Files • Slow it down to half speed without changing the pitch — or shift the pitch without changing the speed • Loop a section, drop markers, and drill the hard bar until it's yours • Record over the top, in sync: the latency is measured on your device, not guessed • Overdub, mix and export

SCORES • Guitar Pro files and chord charts, with playback, a mixer and per-track control • Tap the score to move the playhead, drag across it to set a loop

THE JOURNAL • Every session logged: the piece, the tempo, how long you played • Tempo-over-time charts, so you can see the progress you can't feel • Recordings, scores and backing tracks filed with the song they belong to

Practice Studio runs entirely on your device. No account, no sign-up, and it works with the Wi-Fi off.
