# SmartClean AI vs Authenticator© App

The clearest difference is ads: SmartClean AI at none against Authenticator© App's shown. SmartClean AI also leads on review sentiment (48% vs 20%) and iOS requirement (15 vs 17.0). Authenticator© App's advantage is chart position (#42 vs #130). On price, rating, ratings volume and update cadence there is nothing between them.

Both are free to download. SmartClean AI sells 11 in-app purchases, starting at $6.99 per 7 days and Authenticator© App sells 4 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, 4.6 against 4.4. Both are backed by a comparable volume of ratings — 507 and 681 respectively. Written reviews complicate that: 48% of SmartClean AI's written reviews are positive against 20% of Authenticator© App's, so the app with the better star average is not the one people write more warmly about.

SmartClean AI ships an update every 10 days, Authenticator© App every 9 days. The most recent releases landed on September 25, 2026 and September 23, 2026 respectively.
