ReceptionRating · Positive reviews · Number of ratings

MobileID holds the better App Store score, 1.5 against 1.0. Both are backed by a comparable volume of ratings — 15 and 4 respectively. Written reviews complicate that: 0% of MobileID's written reviews are positive against 30% of Web PKI's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

MobileID ships an update every 4 months, Web PKI every 2 months. The most recent releases landed on August 20, 2026 and September 22, 2026 respectively.
