Verdict

The call

The clearest difference is review sentiment: Auth at 87% against Authenticator App's 43%. Auth also leads on monetization model (free with in-app purchases vs subscription). Authenticator App's advantage is ads (none vs shown) and rating (4.6 vs 4.2). On price, update cadence, in-app purchases and iOS requirement there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Authenticator App sells 11 in-app purchases, starting at $5.99 per 7 days 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.

ReceptionRating · Positive reviews · Number of ratings

Authenticator App holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: Authenticator App has 49K ratings behind it against 365, so its average is the more settled of the two. Written reviews complicate that: 43% 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.

UpkeepUpdate frequency

Authenticator App ships an update fortnightly, Auth every 2 weeks. The most recent releases landed on October 15, 2026 and October 4, 2026 respectively.
