# Chemistry AI vs Learn Estonian

The clearest difference is iOS requirement: Learn Estonian at 16.0 against Chemistry AI's 18.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Chemistry AI sells 4 in-app purchases, starting at $4.99 per 7 days and Learn Estonian sells 6 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.
