# Cumulo vs ThinkFast

The clearest difference is iOS requirement: Cumulo at 15.1 against ThinkFast's 17. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Cumulo sells 4 in-app purchases, starting at $3.99 per 7 days and ThinkFast sells 2 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.
