# Progression vs Kairos

The clearest difference is iOS requirement: Kairos at 14.0 against Progression's 17.6. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Progression sells 4 in-app purchases, starting at $6.99 per 7 days and Kairos sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
