Your iPhone becomes a fully-featured, powerful document scanner with SmartScan. You can quickly and easily scan your multipage documents in high quality PDF or JPEG files on your iPhone or iPad. You can then rename and organize them, and send them anywhere. SmartScan uses complex and efficient algorithms to accurately detect document edges, correct their perspective, eliminate shadows, and perfectly contrast text, black on white. You can also choose between color and black-and-white photo modes. Our user interface is powerful and easy to use. With this app you can easily adjust the brightness, color, and rotation of your device. SmartScan offers SuperScan, a scanning mode that captures sharper images, especially in low-light conditions. Acquiring multiple takes of the same scan, SuperScan guarantees the best result. SmartScan also has an "Email to myself" feature that works with a single tap.

Verdict
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.
