# Einstein AI vs Koluba

The clearest difference is iOS requirement: Einstein AI at 15.1 against Koluba's 17.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Einstein AI sells 2 in-app purchases, starting at $4.99 per 7 days and Koluba sells 2 in-app purchases, starting at $12.00 per month. Whichever you choose, the download price is not the number that matters.
