ReceptionRating · Positive reviews · Number of ratings

Authenticator holds the better App Store score, 4.5 against 4.3. Both are backed by a comparable volume of ratings — 61 and 24 respectively. Written reviews complicate that: 0% of Authenticator's written reviews are positive against 50% of Esign's, so the app with the better star average is not the one people write more warmly about.
