Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
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.
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.
