# One Scan vs Scanner app

One Scan and Scanner app both sit at 4.7 stars, but that hides the real split: 100% of Scanner app's written reviews are positive against 26% of One Scan's. Scanner app also leads on iOS requirement (11.0 vs 18.0). One Scan's advantage is ads (none vs shown) and ratings volume (12K vs 116). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. One Scan sells 10 in-app purchases, starting at $3.99 per 7 days and Scanner app sells 4 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for One Scan against 4.7 for Scanner app. That said, the two scores are not equally well evidenced: One Scan has 12K ratings behind it against 116, so its average is the more settled of the two. Written reviews are what separate them: 26% of One Scan's written reviews are positive against 100% of Scanner app's.

One Scan ships an update fortnightly, Scanner app every 10 days. The most recent releases landed on November 7, 2026 and November 3, 2026 respectively.
