# iD Disk vs U8

The clearest difference is rating: U8 at 4.1 against iD Disk's 1.0. U8 also leads on review sentiment (64% vs 50%) and ratings volume (10 vs 1). iD Disk's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price, update cadence and device support there is nothing between them.

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

U8 holds the better App Store score, 4.1 against 1.0. 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: 50% of iD Disk's written reviews are positive against 64% of U8's.

iD Disk ships an update every 2 months, U8 every 6 weeks. The most recent releases landed on October 8, 2026 and October 10, 2026 respectively.
