# Auth vs Authentication App

The clearest difference is rating: Auth at 5.0 against Authentication App's 4.3. Auth also leads on review sentiment (100% vs 74%). Authentication App's advantage is update cadence (every 2 months vs every 38 months) and ratings volume (592 vs 4). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Auth sells 5 one-off in-app purchases and Authentication App sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Auth holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Authentication App has 592 ratings behind it against 4, so its average is the more settled of the two.
