ReceptionRating · Positive reviews · Number of ratings

Merge Object Viewer holds the better App Store score, 4.5 against 4.2. Both are backed by a comparable volume of ratings — 141 and 390 respectively. Written reviews complicate that: 58% of mozaik3D's written reviews are positive against 48% of Merge Object Viewer's, so the app with the better star average is not the one people write more warmly about.
