# Mofu vs 别白干

The clearest difference is update cadence: 别白干 at every 3 days against Mofu's every 11 days. 别白干 also leads on iOS requirement (13.0 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Mofu sells 3 in-app purchases, starting at $0.99 per month and 别白干 sells 4 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
