# ChordProg Ear Trainer vs Estill Exercises

The clearest difference is rating: Estill Exercises at 5.0 against ChordProg Ear Trainer's 4.4. ChordProg Ear Trainer's advantage is review sentiment (75% vs 38%) and monetization model (free with in-app purchases vs subscription). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. ChordProg Ear Trainer sells 2 in-app purchases, starting at $2.99 per month and Estill Exercises sells 1 in-app purchase, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Estill Exercises holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: ChordProg Ear Trainer has 16 ratings behind it against 2, 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 38% of Estill Exercises's, so the app with the better star average is not the one people write more warmly about.

ChordProg Ear Trainer ships an update every 5 days, Estill Exercises every 6 weeks. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
