Verdict

The call

The clearest difference is review sentiment: QRCode Scanner at 100% against 2FA QR Code App's 31%. QRCode Scanner also leads on in-app purchases (none vs 7) and ads (none vs shown). 2FA QR Code App's advantage is rating (4.1 vs 3.5) and update cadence (every 3 weeks vs every 2 months). On price and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

2FA QR Code App holds the better App Store score, 4.1 against 3.5. That said, the two scores are not equally well evidenced: 2FA QR Code App has 458 ratings behind it against 19, so its average is the more settled of the two. Written reviews complicate that: 100% of QRCode Scanner's written reviews are positive against 31% of 2FA QR Code App's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

QRCode Scanner ships an update every 2 months, 2FA QR Code App every 3 weeks. The most recent releases landed on October 2, 2026 and October 3, 2026 respectively.
