Verdict
The clearest difference is rating: Harmony Helper at 3.9 against Vocal Mastery's 3.0. Harmony Helper also leads on update cadence (every 3 weeks vs every 31 months) and ratings volume (186 vs 2). Vocal Mastery's advantage is in-app purchases (none vs 4) and review sentiment (75% vs 49%). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. Harmony Helper sells 4 in-app purchases, starting at $4.99 per month. Vocal Mastery asks for nothing beyond the download.
Harmony Helper holds the better App Store score, 3.9 against 3.0. That said, the two scores are not equally well evidenced: Harmony Helper has 186 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 75% of Vocal Mastery's written reviews are positive against 49% of Harmony Helper's, so the app with the better star average is not the one people write more warmly about.
Vocal Mastery ships an update every 31 months, Harmony Helper every 3 weeks. The most recent releases landed on September 11, 2026 and September 9, 2026 respectively.
