Tap a step to change its accent. Press start to hear it.
Tuner and metronome apps are everywhere, and most of them flicker, drift or look like a settings screen. I wanted one that behaves like a piece of hardware: steady readings, a beat you can trust, and a face you'd want on a music stand.
A tuner that doesn't flicker
Simple tuners lock onto whatever frequency is loudest, and on a bass string that is often a harmonic rather than the note. Musick Companion uses a more careful pitch detector with smoothing on top, so the reading settles instead of jumping around between notes.
A beat you can trust
Timers drift, and a metronome that drifts is useless. Every click is timed by the audio engine itself, down to the sample.
Accents work like a step sequencer: tap a step to change its accent, and the change comes in without restarting the bar. Haptics follow the same pattern.
Shared core, native shell
The app logic lives in a Kotlin Multiplatform module, and Swift handles audio, haptics and the interface. When the Android version comes, it reuses the same logic.
Feels like hardware
There is no default iOS chrome anywhere: a custom tab bar, LED toggles, segmented displays, and two themes (a digital rack unit and a wooden one) in green or amber phosphor. All colours come from design tokens.
What's next
I'm currently building the music theory encyclopedia and a Pro tier with extra themes and sounds.
