ReceptionRating · Positive reviews · Number of ratings

Piary holds the better App Store score, 5.0 against 4.8. Both are backed by a comparable volume of ratings — 6 and 5 respectively. Written reviews complicate that: 75% of Piary's written reviews are positive against 100% of Memlog's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Piary ships an update every 3 weeks, Memlog every 2 months. The most recent releases landed on June 1, 2026 and June 4, 2026 respectively.
