Verdict

The call

The clearest difference is rating: Authenticator App at 4.6 against QR Code Reader's 3.9. Authenticator App also leads on ratings volume (908 vs 139). QR Code Reader's advantage is ads (none vs shown) and review sentiment (50% vs 38%). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Authenticator App sells 12 in-app purchases, starting at $6.99 per 7 days and QR Code Reader sells 3 in-app purchases, starting at $9.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Authenticator App holds the better App Store score, 4.6 against 3.9. That said, the two scores are not equally well evidenced: Authenticator App has 908 ratings behind it against 139, so its average is the more settled of the two. Written reviews complicate that: 38% of Authenticator App's written reviews are positive against 50% of QR Code Reader's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Authenticator App ships an update every 3 weeks, QR Code Reader every 2 weeks. Both last shipped on September 22, 2026.
