# GV vs Screw Identifier

The clearest difference is review sentiment: GV at 50% against Screw Identifier's 0%. GV also leads on in-app purchases (none vs 9). Screw Identifier's advantage is rating (3.5 vs 3.0) and ratings volume (24 vs 2). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Screw Identifier sells 8 in-app purchases, starting at $4.99 per 7 days. GV asks for nothing beyond the download.

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.

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.
