Maestro: Tuner & Metronome

Maestro is a beautiful chromatic tuner, metronome and practice log — a studio-grade instrument that looks and feels as good as it sounds. Built natively for low-latency audio, Maestro detects pitch in real time and drives a smooth 60fps needle, a calm in-tune color cue, and a steady, accurate metronome click. No lag, no clutter.
