# MobileID vs Web PKI

The clearest difference is rating: MobileID at 1.5 against Web PKI's 1.0. MobileID also leads on ratings volume (15 vs 4). Web PKI's advantage is review sentiment (30% vs 0%) and iOS requirement (8.2 vs 11.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

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.

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.
