# iImprov vs Ear training

The clearest difference is price: Ear training at Free against iImprov's $0.99. Ear training also leads on rating (4.5 vs 3.7) and update cadence (every 8 months vs every 24 months). iImprov's advantage is ads (none vs shown) and review sentiment (57% vs 33%). On in-app purchases and device support there is nothing between them.

Ear training is free to download; iImprov costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Ear training holds the better App Store score, 4.5 against 3.7. That said, the two scores are not equally well evidenced: Ear training has 250 ratings behind it against 23, so its average is the more settled of the two. Written reviews complicate that: 57% of iImprov's written reviews are positive against 33% of Ear training's, so the app with the better star average is not the one people write more warmly about.

iImprov ships an update every 24 months, Ear training every 8 months. The most recent releases landed on November 6, 2026 and November 7, 2026 respectively.
