# AI Clean vs Authenticator

The clearest difference is ads: Authenticator at none against AI Clean's shown. AI Clean's advantage is rating (4.5 vs 4.0) and review sentiment (62% vs 33%). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. AI Clean sells 9 in-app purchases, starting at $5.99 per 7 days and Authenticator sells 3 in-app purchases, starting at $9.99 per 7 days. Whichever you choose, the download price is not the number that matters.

AI Clean holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: AI Clean has 1.2K ratings behind it against 16, so its average is the more settled of the two. Written reviews point the same way: 62% of AI Clean's written reviews are positive against 33% of Authenticator's.

AI Clean ships an update every 2 weeks, Authenticator every 9 days. The most recent releases landed on November 8, 2026 and November 9, 2026 respectively.
