Verdict

The call

The clearest difference is rating: Authenticator App at 4.7 against PubReader's 2.8. Authenticator App also leads on ratings volume (34K vs 4) and update cadence (every 9 days vs every 2 months). PubReader's advantage is review sentiment (67% vs 45%). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Authenticator App holds the better App Store score, 4.7 against 2.8. That said, the two scores are not equally well evidenced: Authenticator App has 34K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 45% of Authenticator App's written reviews are positive against 67% of PubReader'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 9 days, PubReader every 2 months. The most recent releases landed on September 25, 2026 and June 4, 2026 respectively.
