Maestro: Tuner & Metronome

A studio-grade tuner and metronome that finally looks the part. Buttery 60fps needle, sample-accurate click, haptic tempo — tune in two taps.

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. Open the app and you're tuning in two taps.

PRO Maestro is free to use as a chromatic tuner and basic metronome. Maestro Pro unlocks instrument presets, alternate tunings & temperaments, the drone generator, every tuner gauge, full practice insights, and CSV/PDF export — a one-time $4.99 unlock. No ads, ever.

Tune in. Keep time. Practice better.
