# EM3D vs OpticALLY 3D Scan

The clearest difference is review sentiment: OpticALLY 3D Scan at 100% against EM3D's 33%. EM3D's advantage is rating (4.0 vs 3.0) and in-app purchases (none vs 2). On price, ratings volume, ads and monetization model there is nothing between them.

Both are free to download. OpticALLY 3D Scan sells 2 in-app purchases, starting at $4.99 per month. EM3D asks for nothing beyond the download.

EM3D holds the better App Store score, 4.0 against 3.0. Both are backed by a comparable volume of ratings — 5 and 2 respectively. Written reviews complicate that: 33% of EM3D's written reviews are positive against 100% of OpticALLY 3D Scan's, so the app with the better star average is not the one people write more warmly about.
