# Esspresso vs Solo Harmony

The clearest difference is rating: Solo Harmony at 4.0 against Esspresso's 3.3. Solo Harmony also leads on price ($0.99 vs $9.99) and device support (3 vs 1). Esspresso's advantage is review sentiment (40% vs 20%) and ratings volume (17 vs 3). On update cadence, ads, in-app purchases and monetization model there is nothing between them.

Esspresso costs $9.99 and Solo Harmony $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Solo Harmony holds the better App Store score, 4.0 against 3.3. That said, the two scores are not equally well evidenced: Esspresso has 17 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 40% of Esspresso'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.

Esspresso ships an update every 9 months, Solo Harmony every 7 months. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
