# Auth vs Authenticator App

The clearest difference is review sentiment: Auth at 87% against Authenticator App's 25%. Authenticator App's advantage is ads (none vs shown) and rating (4.5 vs 4.2). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Auth sells 2 in-app purchases, starting at $3.99 per 7 days and Authenticator App sells 21 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Authenticator App holds the better App Store score, 4.5 against 4.2. Both are backed by a comparable volume of ratings — 365 and 1.8K respectively. Written reviews complicate that: 87% of Auth's written reviews are positive against 25% of Authenticator App's, so the app with the better star average is not the one people write more warmly about.

Auth ships an update every 2 weeks, Authenticator App monthly. The most recent releases landed on September 30, 2026 and September 28, 2026 respectively.
