ReceptionRating · Positive reviews · Number of ratings

DDLock holds the better App Store score, 2.9 against 2.0. That said, the two scores are not equally well evidenced: DDLock has 99 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 20% of DDLock's written reviews are positive against 25% of Blackview Security's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

DDLock ships an update every 4 months, Blackview Security every 2 months. The most recent releases landed on October 10, 2026 and September 21, 2026 respectively.
