# QR Code Reader & Scanner Pro vs PDF Scanner

QR Code Reader & Scanner Pro also leads on update cadence (every 10 days vs every 4 weeks) and ratings volume (46 vs 6).

Written reviews complicate that: 75% of QR Code Reader & Scanner Pro's written reviews are positive against 0% of PDF Scanner's, so the app with the better star average is not the one people write more warmly about.
