# Aidisk vs U8

The clearest difference is review sentiment: U8 at 64% against Aidisk's 9%. U8 also leads on rating (4.1 vs 3.0) and ratings volume (10 vs 1). Aidisk'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. Aidisk asks for nothing beyond the download.

U8 holds the better App Store score, 4.1 against 3.0. 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: 9% of Aidisk's written reviews are positive against 64% of U8's.

Both ship on a similar rhythm, roughly every 6 weeks. The most recent releases landed on October 7, 2026 and October 10, 2026 respectively.
