# Harmonic Analysis vs ChordProg Ear Trainer

The clearest difference is review sentiment: ChordProg Ear Trainer at 75% against Harmonic Analysis's 43%. ChordProg Ear Trainer also leads on device support (3 vs 1) and iOS requirement (14.0 vs 17.6). Harmonic Analysis's advantage is rating (4.7 vs 4.4) and update cadence (every 2 days vs every 5 days). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Harmonic Analysis sells 3 in-app purchases, starting at $3.99 per month and ChordProg Ear Trainer sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

Harmonic Analysis holds the better App Store score, 4.7 against 4.4. Both are backed by a comparable volume of ratings — 22 and 16 respectively. Written reviews complicate that: 43% of Harmonic Analysis's written reviews are positive against 75% of ChordProg Ear Trainer's, so the app with the better star average is not the one people write more warmly about.

Harmonic Analysis ships an update every 2 days, ChordProg Ear Trainer every 5 days. Both last shipped on November 2, 2026.
