# Fax vs Authenticator

The clearest difference is rating: Authenticator at 4.3 against Fax's 3.5. Fax's advantage is ads (none vs shown) and iOS requirement (11.0 vs 15.0). On price, review sentiment, ratings volume and in-app purchases there is nothing between them.

Both are free to download. Fax sells 2 in-app purchases, starting at $4.99 per 7 days and Authenticator sells 6 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Authenticator holds the better App Store score, 4.3 against 3.5. Both are backed by a comparable volume of ratings — 35 and 32 respectively. Written reviews complicate that: 8% of Fax's written reviews are positive against 0% of Authenticator's, so the app with the better star average is not the one people write more warmly about.
