# Purus vs Onyx

The clearest difference is ratings volume: Purus at 5 against Onyx's 1. Purus also leads on iOS requirement (16.0 vs 26.2). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Purus sells 2 in-app purchases, starting at $4.99 per month and Onyx sells 1 one-off in-app purchase. 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 Purus against 5.0 for Onyx. That said, the two scores are not equally well evidenced: Purus has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
