ReceptionRating · Positive reviews · Number of ratings

Violin Tuner holds the better App Store score, 4.8 against 3.0. That said, the two scores are not equally well evidenced: Violin Tuner has 53 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 62% of Chord NOTE's written reviews are positive against 50% of Violin Tuner's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Chord NOTE ships an update every 2 months, Violin Tuner every 8 months. Both last shipped on November 6, 2026.
