# COMPOUND vs Pepmunk

Both are free to download. COMPOUND sells 5 in-app purchases, starting at $6.99 per 7 days and Pepmunk sells 2 in-app purchases, starting at $4.99 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 COMPOUND against 4.9 for Pepmunk. That said, the two scores are not equally well evidenced: Pepmunk has 43 ratings behind it against 4, so its average is the more settled of the two.
