Verdict

The call

The clearest difference is review sentiment: AirScan at 73% against One Scan's 26%. AirScan also leads on in-app purchases (none vs 10) and iOS requirement (13.0 vs 26.0). One Scan's advantage is ratings volume (12K vs 455) and rating (4.7 vs 4.4). On price, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

One Scan holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: One Scan has 12K ratings behind it against 455, so its average is the more settled of the two. Written reviews complicate that: 73% of AirScan's written reviews are positive against 26% of One Scan's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

AirScan ships an update every 2 months, One Scan monthly. The most recent releases landed on October 21, 2026 and October 26, 2026 respectively.
