# MoonFlow vs DoLDoL

The clearest difference is device support: MoonFlow at 3 against DoLDoL's 1. MoonFlow also leads on iOS requirement (15.0 vs 18.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. MoonFlow sells 3 in-app purchases, starting at $3.99 per month and DoLDoL sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
