Verdict

The call

The clearest difference is review sentiment: STL Master at 86% against 3d Scanner App™'s 45%.

On price, update cadence, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

3d Scanner App™ ships an update every 4 weeks, STL Master monthly. The most recent releases landed on October 18, 2026 and October 15, 2026 respectively.
