ReceptionRating · Positive reviews · Number of ratings

UGREEN NAS holds the better App Store score, 4.1 against 1.7. That said, the two scores are not equally well evidenced: UGREEN NAS has 327 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 53% of UGREEN NAS's written reviews are positive against 67% of VBook Scan's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

UGREEN NAS ships an update every 3 weeks, VBook Scan every 2 weeks. The most recent releases landed on November 7, 2026 and November 5, 2026 respectively.
