# Interval Calculator & Quiz vs Interval Ear Training

The clearest difference is rating: Interval Calculator & Quiz at 4.4 against Interval Ear Training's 4.0. Interval Calculator & Quiz also leads on ratings volume (7 vs 1). Interval Ear Training's advantage is update cadence (every 3 days vs monthly) and review sentiment (100% vs 80%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Interval Calculator & Quiz sells 1 one-off in-app purchase and Interval Ear Training sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Interval Calculator & Quiz holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: Interval Calculator & Quiz has 7 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 80% of Interval Calculator & Quiz'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.

Interval Calculator & Quiz ships an update monthly, Interval Ear Training every 3 days. The most recent releases landed on November 3, 2026 and October 28, 2026 respectively.
