ReceptionRating · Positive reviews · Number of ratings

TurboScan™ Pro holds the better App Store score, 4.9 against 4.4. That said, the two scores are not equally well evidenced: TurboScan™ Pro has 297K ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 96% of TurboScan™ Pro's written reviews are positive against 100% of Smart PDF Document Scanner's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

TurboScan™ Pro ships an update every 3 months, Smart PDF Document Scanner every 6 months. The most recent releases landed on October 29, 2026 and October 11, 2026 respectively.
