# Pre vs Math AI

The clearest difference is device support: Pre at 3 against Math AI's 1. On price, ads, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. Pre sells 1 in-app purchase, starting at $4.99 per month and Math AI sells 2 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.
