# 3d Scanner App™ vs STL Master

The clearest difference is review sentiment: STL Master at 86% against 3d Scanner App™'s 45%. STL Master also leads on in-app purchases (none vs 8) and ads (none vs shown). 3d Scanner App™'s advantage is ratings volume (16K vs 49) and rating (4.5 vs 4.2). On price, update cadence, device support 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. STL Master asks for nothing beyond the download.

3d Scanner App™ holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: 3d Scanner App™ has 16K ratings behind it against 49, so its average is the more settled of the two. Written reviews complicate that: 45% of 3d Scanner App™'s written reviews are positive against 86% of STL Master's, so the app with the better star average is not the one people write more warmly about.

3d Scanner App™ ships an update every 4 weeks, STL Master monthly. The most recent releases landed on October 19, 2026 and October 15, 2026 respectively.
