# U8 vs F

The clearest difference is rating: F at 5.0 against U8's 4.1. F also leads on review sentiment (100% vs 64%) and in-app purchases (none vs 1). U8's advantage is ratings volume (10 vs 1). On price, device support and iOS requirement there is nothing between them.

Both are free to download. U8 sells 1 one-off in-app purchase. F asks for nothing beyond the download.

F holds the better App Store score, 5.0 against 4.1. That said, the two scores are not equally well evidenced: U8 has 10 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 64% of U8's written reviews are positive against 100% of F's.
