ReceptionRating · Positive reviews · Number of ratings

Rentbrella holds the better App Store score, 4.4 against 2.6. That said, the two scores are not equally well evidenced: Rentbrella has 56 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 48% of Rentbrella's written reviews are positive against 95% of Keyless Authenticator's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Rentbrella ships an update every 2 months, Keyless Authenticator every 5 weeks. The most recent releases landed on October 18, 2026 and October 15, 2026 respectively.
