ReceptionRating · Positive reviews · Number of ratings

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 46, so its average is the more settled of the two. Written reviews complicate that: 51% of Emu50g'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.

UpkeepUpdate frequency

Emu50g ships an update every 6 weeks, 3d Scanner App™ monthly. The most recent releases landed on October 17, 2026 and October 20, 2026 respectively.
