Made for practice
The headstock on screen looks like the one in your hands. Play a string: the peg to turn lights up, an arrow on it shows which way, the meter shows how far in cents. Green means in tune.
Hears acoustic and electric guitars, 4- and 5-string basses down to B0 and ukuleles through the phone microphone, with talking and room noise around.
44 tunings: standard, half and whole step down, Drop D, C, B and A, open tunings, DADGAD, 7-string, ukulele with high or low G, D tuning and baritone.
Your own instruments with 1 to 12 strings: mandolin, banjo, balalaika, 8-string.
Chromatic mode. Reference A from 430 to 450 Hz. Note names as C D E, Do Re Mi or with H.
Metronome: tempo, bars with accents and skipped beats, subdivisions, a drum mode with ready rhythms and several metronomes at once. Recorded sounds of real metronomes; it keeps playing with the screen locked.
Sound never leaves your phone. 50 languages. iPhone with iOS 15 or later.
