TunerMetro
TunerMetro combines a tuner and metronome in one practical music tool for performance and daily practice. The tuner shows both cents and the detected frequency in hertz, while the metronome provides direct tempo control and tap-tempo detection.
Two Music Tools in One App
The app brings two essential practice tools together: instrument tuning and tempo practice. Keeping the tuner and metronome in the same app makes it easy to move directly from tuning an instrument to rehearsing with a steady pulse.
Instrument Tuner with Hertz Display
The tuner supports a wide range of acoustic and electric instruments, including piano, acoustic and electric guitar, bass, strings, brass, woodwinds, and timpani. It displays pitch deviation in cents, the detected frequency in hertz, and the input level. Pitch-detection processing is designed to keep note identification stable across octave ranges.
The original specification states tuning resolution of ±0.001 semitone or ±0.1 cent. Rather than making this the main selling point, the page emphasizes the practical combination of note, cent, and hertz readouts.
Metronome and Tap Tempo
The metronome uses a virtual physical-style tempo knob and supports multiple beat setups. A Tap Tempo button detects the tempo from repeated taps, providing a quick way to match an existing rhythm or estimate a performance tempo.
Background Audio
The input-level display helps you monitor the incoming audio signal while tuning.
Background Audio allows TunerMetro to continue operating while another compatible task or app is in use, making it more practical during practice and performance.
