# Authenticator App vs PubReader

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.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

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.

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.
