ReceptionRating · Positive reviews · Number of ratings

Screw Identifier holds the better App Store score, 3.5 against 3.0. That said, the two scores are not equally well evidenced: Screw Identifier has 24 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 50% of GV's written reviews are positive against 0% of Screw Identifier's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

GV ships an update every 8 months, Screw Identifier every 5 months. The most recent releases landed on October 6, 2026 and October 25, 2026 respectively.
