# MnemonicWords vs KnowLang

Both are free to download. MnemonicWords sells 11 in-app purchases, starting at $1.99 per month and KnowLang sells 7 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for MnemonicWords against 5.0 for KnowLang. That said, the two scores are not equally well evidenced: MnemonicWords has 8 ratings behind it against 1, so its average is the more settled of the two.
