# Sixfast vs Dive World

The clearest difference is rating: Sixfast at 4.4 against Dive World's 3.0. Sixfast also leads on ratings volume (223 vs 2) and device support (4 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Sixfast sells 20 in-app purchases, starting at $5.99 per month and Dive World sells 2 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.
