Verdict
The clearest difference is price: 3d Scanner App™ at Free against Emu50g's $8.99. 3d Scanner App™ also leads on rating (4.5 vs 4.0) and ratings volume (16K vs 46). Emu50g's advantage is in-app purchases (none vs 8) and ads (none vs shown). On review sentiment, update cadence and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
3d Scanner App™ is free to download; Emu50g costs $8.99 up front. 3d Scanner App™ sells 8 in-app purchases, starting at $2.99 per 7 days. Emu50g asks for nothing beyond the download.
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.
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.
