Maestro: Tuner & Metronome

Maestro is the most beautiful way to tune, keep tempo, and build a daily practice habit — a studio-grade instrument that finally looks and feels as good as it sounds. Built natively for low-latency audio, Maestro detects pitch in real time and drives a buttery 60fps needle, a calm in-tune color cue, and a sample-accurate metronome click. No lag, no clutter — just the tools serious players reach for every day. A PRECISION TUNER • Real-time chromatic pitch detection — fast, stable, accurate • Instrument presets: guitar, bass, violin, ukulele, brass, voice • Cents needle + strobe view + a green "locked" cue when you nail it • Haptic tick the moment you hit the note — tune without watching • Alternate tunings, transposition, and adjustable A4 (415–466 Hz) A ROCK-SOLID METRONOME • Sample-accurate click that never drifts • Tap-tempo, subdivisions, accents, and custom time signatures • Haptic tempo pulse you can feel through the table or your pocket • Count-in and tempo setlists for working through a piece A PRACTICE HABIT THAT STICKS • Drone / tone generator for ear training and intonation • Practice timer with an honest day streak • Session log: time practiced, % in tune, tempos mastered • Insights charts that show your progress over time DESIGN-FIRST Deep charcoal surfaces, a single precise green in-tune cue, instrument-grade gauges, and one clean grotesk typeface — a polished, dark, studio-grade interface.
