ReceptionRating · Positive reviews · Number of ratings

Inventry holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Proton Authenticator has 242 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 56% of Proton Authenticator's written reviews are positive against 0% of Inventry's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Proton Authenticator ships an update weekly, Inventry every 5 days. The most recent releases landed on October 16, 2026 and October 10, 2026 respectively.
