ReceptionRating · Positive reviews · Number of ratings

Pro Guitar Tuner holds the better App Store score, 4.7 against 3.1. That said, the two scores are not equally well evidenced: Pro Guitar Tuner has 10K ratings behind it against 15, so its average is the more settled of the two. Written reviews complicate that: 65% of Pro Guitar Tuner's written reviews are positive against 80% of 12 String Guitar Tuner's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Pro Guitar Tuner ships an update monthly, 12 String Guitar Tuner every 2 months. The most recent releases landed on October 22, 2026 and October 8, 2026 respectively.
