The clearest difference is price: Chord X at Free against Interval Ear Trainer's $1.99. Chord X also leads on update cadence (every 6 weeks vs every 13 months) and rating (4.2 vs 3.9). Interval Ear Trainer's advantage is in-app purchases (none vs 3) and ads (none vs shown). On review sentiment and device support there is nothing between them.

Written reviews complicate that: 67% of Interval Ear Trainer's written reviews are positive against 60% of Chord X's, so the app with the better star average is not the one people write more warmly about.

Interval Ear Trainer ships an update every 13 months, Chord X every 6 weeks. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
