# Marine Engine ASMR vs 3D Printing

The clearest difference is rating: Marine Engine ASMR at 4.0 against 3D Printing's 2.9. Marine Engine ASMR also leads on in-app purchases (none vs 2). 3D Printing's advantage is review sentiment (17% vs 0%) and ratings volume (36 vs 8). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. 3D Printing sells 2 in-app purchases, starting at $19.99 per month. Marine Engine ASMR asks for nothing beyond the download.

Marine Engine ASMR holds the better App Store score, 4.0 against 2.9. Both are backed by a comparable volume of ratings — 8 and 36 respectively. Written reviews complicate that: 0% of Marine Engine ASMR's written reviews are positive against 17% of 3D Printing's, so the app with the better star average is not the one people write more warmly about.
