# Authenticator vs Patent AI

The clearest difference is rating: Authenticator at 5.0 against Patent AI's 4.0. Authenticator also leads on device support (4 vs 2) and price ($0.99 vs $1.99). Patent AI's advantage is update cadence (every 4 days vs every 2 months) and review sentiment (100% vs 75%). On ratings volume, ads, in-app purchases and monetization model there is nothing between them.

Authenticator costs $0.99 and Patent AI $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Authenticator holds the better App Store score, 5.0 against 4.0. Both are backed by a comparable volume of ratings — 3 and 3 respectively. Written reviews complicate that: 75% of Authenticator's written reviews are positive against 100% of Patent AI's, so the app with the better star average is not the one people write more warmly about.

Authenticator ships an update every 2 months, Patent AI every 4 days. The most recent releases landed on October 10, 2026 and October 5, 2026 respectively.
