# iKnow! vs Boki Master Pro

The clearest difference is device support: iKnow! at 4 against Boki Master Pro's 2. iKnow! also leads on iOS requirement (14.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. iKnow! sells 10 one-off in-app purchases and Boki Master Pro sells 3 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.
