ReceptionRating · Positive reviews · Number of ratings

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: 50% of Letscappella'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.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on June 6, 2026 and September 25, 2026 respectively.
