# Avast One vs Authenticator App

Avast One and Authenticator App both sit at 4.7 stars, but that hides the real split: 100% of Authenticator App's written reviews are positive against 54% of Avast One's. Authenticator App also leads on iOS requirement (15.0 vs 17.0). Avast One's advantage is monetization model (freemium vs subscription) and ads (none vs shown). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. Avast One sells 19 in-app purchases, starting at $2.49 per month and Authenticator App sells 5 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for Avast One against 4.6 for Authenticator App. That said, the two scores are not equally well evidenced: Avast One has 100K ratings behind it against 84, so its average is the more settled of the two. Written reviews are what separate them: 54% of Avast One's written reviews are positive against 100% of Authenticator App's.
