ReceptionRating · Positive reviews · Number of ratings

dMemo holds the better App Store score, 5.0 against 2.7. That said, the two scores are not equally well evidenced: Notes Lock has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 75% of dMemo's written reviews are positive against 87% of Notes Lock's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

dMemo ships an update monthly, Notes Lock every 3 months. The most recent releases landed on September 30, 2026 and October 12, 2026 respectively.
