Verdict
The clearest difference is rating: Authenticator App at 4.8 against Auth's 4.2. Authenticator App also leads on ads (none vs shown). Auth's advantage is review sentiment (87% vs 72%) and ratings volume (365 vs 32). On price, update cadence, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Authenticator App sells 3 in-app purchases, starting at $1.99 per month and Auth sells 2 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Authenticator App holds the better App Store score, 4.8 against 4.2. That said, the two scores are not equally well evidenced: Auth has 365 ratings behind it against 32, so its average is the more settled of the two. Written reviews complicate that: 72% of Authenticator App's written reviews are positive against 87% of Auth's, so the app with the better star average is not the one people write more warmly about.
Authenticator App ships an update fortnightly, Auth every 2 weeks. The most recent releases landed on September 29, 2026 and September 30, 2026 respectively.
