# SmartScan Pro vs One Scan

SmartScan Pro and One Scan both sit at 4.5 stars, but that hides the real split: 68% of SmartScan Pro's written reviews are positive against 26% of One Scan's. SmartScan Pro also leads on iOS requirement (12.0 vs 18.0). One Scan's advantage is update cadence (monthly vs every 2 months) and ratings volume (12K vs 1.4K). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. SmartScan Pro sells 2 in-app purchases, starting at $1.99 per month and One Scan sells 10 in-app purchases, starting at $3.99 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 — 4.5 for SmartScan Pro against 4.7 for One Scan. That said, the two scores are not equally well evidenced: One Scan has 12K ratings behind it against 1.4K, so its average is the more settled of the two. Written reviews are what separate them: 68% of SmartScan Pro's written reviews are positive against 26% of One Scan's.

SmartScan Pro ships an update every 2 months, One Scan monthly. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
