# PDF Scanner vs 3d Scanner App™

The clearest difference is rating: PDF Scanner at 5.0 against 3d Scanner App™'s 4.5. PDF Scanner also leads on in-app purchases (none vs 8). 3d Scanner App™'s advantage is review sentiment (45% vs 10%) and update cadence (monthly vs every 52 months). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. 3d Scanner App™ sells 8 in-app purchases, starting at $2.99 per 7 days. PDF Scanner asks for nothing beyond the download.

PDF Scanner holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: 3d Scanner App™ has 16K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 10% of PDF Scanner'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.

PDF Scanner ships an update every 52 months, 3d Scanner App™ monthly. The most recent releases landed on November 2, 2026 and November 11, 2026 respectively.
