# i vs U8

The clearest difference is rating: i at 5.0 against U8's 4.0. i also leads on in-app purchases (none vs 1) and ads (none vs shown). U8's advantage is ratings volume (9 vs 1). On price and device support there is nothing between them.

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

i holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: U8 has 9 ratings behind it against 1, so its average is the more settled of the two.
