ReceptionRating · Positive reviews · Number of ratings

ChordProg Ear Trainer holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: ChordProg Ear Trainer has 16 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 75% of ChordProg Ear Trainer's written reviews are positive against 100% of Interval Ear Training's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

ChordProg Ear Trainer ships an update every 5 days, Interval Ear Training every 3 days. The most recent releases landed on October 7, 2026 and October 17, 2026 respectively.
