# i vs U8

The clearest difference is review sentiment: U8 at 64% against i's 12%. U8 also leads on rating (4.0 vs 2.1). i's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price, update cadence, device support and iOS requirement 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.

U8 holds the better App Store score, 4.0 against 2.1. That said, the two scores are not equally well evidenced: i has 80 ratings behind it against 9, so its average is the more settled of the two. Written reviews point the same way: 12% of i's written reviews are positive against 64% of U8's.

i ships an update every 3 months, U8 every 6 weeks. The most recent releases landed on July 5, 2026 and September 17, 2026 respectively.
