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.

Verdict

The call

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.
