# YoSu vs Fast

The clearest difference is in-app purchases: YoSu at none against Fast's 3. YoSu also leads on ads (none vs shown) and iOS requirement (13.0 vs 15.0). On price and device support there is nothing between them.

Both are free to download. Fast sells 3 in-app purchases, starting at $4.99 per 7 days. YoSu asks for nothing beyond the download.
