# Hague Screw Thread Calculator vs 3d Scanner App™

The clearest difference is review sentiment: Hague Screw Thread Calculator at 82% against 3d Scanner App™'s 45%. Hague Screw Thread Calculator also leads on in-app purchases (none vs 8) and ads (none vs shown). 3d Scanner App™'s advantage is rating (4.5 vs 4.0) and ratings volume (16K vs 5). On price, update cadence and iOS requirement there is nothing between them.

Both are free to download. 3d Scanner App™ sells 8 in-app purchases, starting at $2.99 per 7 days. Hague Screw Thread Calculator asks for nothing beyond the download.

3d Scanner App™ holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: 3d Scanner App™ has 16K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 82% of Hague Screw Thread Calculator's written reviews are positive against 45% of 3d Scanner App™'s, so the app with the better star average is not the one people write more warmly about.

Hague Screw Thread Calculator ships an update every 2 months, 3d Scanner App™ monthly. The most recent releases landed on October 20, 2026 and October 26, 2026 respectively.
