About this app
Green Tune is an offline music practice app that brings together the essential tools for guitar and other instruments in one place.
The chromatic tuner analyzes microphone input in real time directly on your device, displaying the detected note, octave, frequency, and pitch deviation in cents. The reference pitch can be adjusted from 432 Hz to 446 Hz.
The metronome supports tempos from 30 to 300 BPM, multiple time signatures, and note subdivisions. You can customize accents or rests for each beat, set a practice timer, enable automatic tempo increases, and improve your timing by alternating between audible and silent measures. Frequently used settings can be saved as presets.
For songs with an unknown tempo, simply tap the screen repeatedly along with the beat. Green Tune analyzes your recent taps and estimates the song's BPM.
