# Marble vs Simplifast

The clearest difference is device support: Simplifast at 3 against Marble's 1. Simplifast also leads on iOS requirement (14.0 vs 17.2). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Marble sells 3 in-app purchases, starting at $1.99 per month and Simplifast sells 2 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.
