Hey all! 👋
I’m new here & launching ChromTuner today, my first macOS app.
I know this is pretty niche, but I built it for myself. I wanted a tuner that felt like it actually belonged on a Mac. Fast, native, always nearby, and not trying to be more complicated than it needs to be.
Chromatic Tuner lives in your menu bar, opens in a small 360px popover, and lets you tune without breaking your flow. It works with your Mac’s built-in mic or any Core Audio input, so you can use a USB interface if that’s how you already record or practice.
A few things I cared about while building it:
It runs fully offline
Audio never leaves your Mac
No account
No telemetry
No subscription
Native Apple Silicon + Intel build
15 instrument presets
Capo, transpose, custom A4, and historical temperaments
LED meter and strobe mode
It’s not trying to replace a big studio setup. It’s just a small, focused Mac app for tuning guitars, basses, strings, or anything pitched, without opening a browser tab or reaching for your phone.
There’s also a free browser version if you just want to try the pitch engine first. The Mac app is $6.99 once, with lifetime 1.x updates. This is my first macOS launch, so I’d genuinely love your feedback. Especially from musicians, Mac people, and anyone who still has too many tiny utility apps in their menu bar.
Cheers,
Clemens
