ReceptionRating · Positive reviews · Number of ratings

Lens Scan holds the better App Store score, 4.6 against 3.2. That said, the two scores are not equally well evidenced: Lens Scan has 18K ratings behind it against 109, so its average is the more settled of the two. Written reviews complicate that: 54% of Rock Identifier Stone Scanner!'s written reviews are positive against 26% of Lens Scan's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Rock Identifier Stone Scanner! ships an update monthly, Lens Scan every 10 days. The most recent releases landed on August 29, 2026 and September 24, 2026 respectively.
