# Keet vs Unknown app

The clearest difference is ratings volume: Keet at 10 against Unknown app's 1. On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Keet sells 2 in-app purchases, starting at $14.99 per month and Unknown app sells 6 in-app purchases, starting at $2.99 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 — 5.0 for Keet against 5.0 for Unknown app. That said, the two scores are not equally well evidenced: Keet has 10 ratings behind it against 1, so its average is the more settled of the two.
