# dMemo vs Notes Lock

The clearest difference is rating: dMemo at 5.0 against Notes Lock's 2.7. dMemo also leads on in-app purchases (none vs 1) and update cadence (monthly vs every 3 months). Notes Lock's advantage is review sentiment (87% vs 75%) and ratings volume (6 vs 1). On price, ads and device support there is nothing between them.

Both are free to download. Notes Lock sells 1 one-off in-app purchase. dMemo asks for nothing beyond the download.

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.

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