# MAI vs Knodo

The clearest difference is device support: MAI at 3 against Knodo's 1. MAI also leads on iOS requirement (17.6 vs 26.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. MAI sells 3 in-app purchases, starting at $12.99 per month and Knodo sells 3 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.
