# Polymer vs 3d Scanner App™

The clearest difference is review sentiment: Polymer at 81% against 3d Scanner App™'s 45%. Polymer also leads on ads (none vs shown) and rating (4.7 vs 4.5). 3d Scanner App™'s advantage is ratings volume (16K vs 1.7K). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Polymer sells 4 one-off in-app purchases and 3d Scanner App™ sells 8 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Polymer holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: 3d Scanner App™ has 16K ratings behind it against 1.7K, so its average is the more settled of the two. Written reviews point the same way: 81% of Polymer's written reviews are positive against 45% of 3d Scanner App™'s.

Both ship on a similar rhythm, roughly monthly. The most recent releases landed on October 22, 2026 and October 25, 2026 respectively.
