# Fretuoso vs Interval Ear Trainer

The clearest difference is price: Fretuoso at Free against Interval Ear Trainer's $1.99. Fretuoso also leads on rating (4.6 vs 3.9) and update cadence (every 11 days vs every 13 months). Interval Ear Trainer's advantage is in-app purchases (none vs 12) and ads (none vs shown). On review sentiment and device support there is nothing between them.

Fretuoso is free to download; Interval Ear Trainer costs $1.99 up front. Fretuoso sells 12 one-off in-app purchases. Interval Ear Trainer asks for nothing beyond the download.

Fretuoso holds the better App Store score, 4.6 against 3.9. That said, the two scores are not equally well evidenced: Fretuoso has 954 ratings behind it against 44, so its average is the more settled of the two. Written reviews complicate that: 61% of Fretuoso's written reviews are positive against 67% of Interval Ear Trainer's, so the app with the better star average is not the one people write more warmly about.

Fretuoso ships an update every 11 days, Interval Ear Trainer every 13 months. The most recent releases landed on October 20, 2026 and October 21, 2026 respectively.
