ReceptionRating · Positive reviews · Number of ratings

Authenticator App ⋆ holds the better App Store score, 4.0 against 3.7. That said, the two scores are not equally well evidenced: Authenticator App ⋆ has 47 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 67% of NapCat's written reviews are positive against 0% of Authenticator App ⋆'s, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

NapCat ships an update every 4 months, Authenticator App ⋆ every 9 days. The most recent releases landed on September 16, 2026 and September 22, 2026 respectively.
