# Duo Authenticator vs Authenticator App

The clearest difference is review sentiment: Duo Authenticator at 50% against Authenticator App's 0%. Authenticator App's advantage is ads (none vs shown) and rating (4.7 vs 4.2). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Duo Authenticator sells 3 in-app purchases, starting at $3.99 per 7 days and Authenticator App sells 3 in-app purchases, starting at $5.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Authenticator App holds the better App Store score, 4.7 against 4.2. Both are backed by a comparable volume of ratings — 24 and 94 respectively. Written reviews complicate that: 50% of Duo Authenticator's written reviews are positive against 0% of Authenticator App's, so the app with the better star average is not the one people write more warmly about.
