Verdict
The clearest difference is rating: RIA DigiDoc at 3.0 against Finnish Authenticator's 1.3. RIA DigiDoc also leads on update cadence (every 3 months vs every 6 months). Finnish Authenticator's advantage is ratings volume (16 vs 4) and iOS requirement (11.0 vs 18.0). On price, review sentiment, 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.
RIA DigiDoc holds the better App Store score, 3.0 against 1.3. Both are backed by a comparable volume of ratings — 4 and 16 respectively. Written reviews complicate that: 0% of RIA DigiDoc's written reviews are positive against 4% of Finnish Authenticator's, so the app with the better star average is not the one people write more warmly about.
RIA DigiDoc ships an update every 3 months, Finnish Authenticator every 6 months. The most recent releases landed on October 12, 2026 and October 24, 2026 respectively.
