# BrainHook vs Vocabulary Builder

The clearest difference is iOS requirement: BrainHook at 13.0 against Vocabulary Builder's 15.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. BrainHook sells 2 in-app purchases, starting at $9.99 per month and Vocabulary Builder sells 1 in-app purchase, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.
