Verdict

The call

The clearest difference is in-app purchases: Solo Harmony at none against Sing Harmonies's 14. Solo Harmony also leads on rating (4.0 vs 3.7) and price ($0.99 vs $1.99). Sing Harmonies's advantage is review sentiment (55% vs 20%) and ratings volume (24 vs 3). On update cadence, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Solo Harmony holds the better App Store score, 4.0 against 3.7. That said, the two scores are not equally well evidenced: Sing Harmonies has 24 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 55% of Sing Harmonies's written reviews are positive against 20% of Solo Harmony's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Sing Harmonies ships an update every 6 months, Solo Harmony every 7 months. The most recent releases landed on October 19, 2026 and October 16, 2026 respectively.
