Learn to recognize chord progressions by ear with real recorded music. ChordProg Ear Trainer has exercises for chord, interval and scale practice, from identifying individual sounds to following a whole progression. Listen to a clip and name the chords in order. Replay a passage when you need another listen, and switch between chord names and Roman numerals to practice recognizing each chord's role in the key. More than 500 recorded clips give you practice across different keys and voicings. Focus on the sounds you want to recognize. Practice telling chord types apart, hearing the distance between two notes or identifying a scale as it plays. Work through short levels and return to the ones you find difficult. Your results and daily streak help you keep track of your practice. When you want to understand what you heard, look it up in the chord, interval and scale dictionaries. You can also tap notes on the piano to find matching chords and scales. Try introductory levels without a subscription. Premium gives you full access to the chord, interval, scale and chord progression exercises through an auto-renewing monthly or yearly subscription.

Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
