# uDisk vs U8

The clearest difference is ads: uDisk at none against U8's shown. uDisk also leads on rating (4.3 vs 4.0) and review sentiment (84% vs 64%). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. uDisk sells 1 one-off in-app purchase and U8 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

uDisk holds the better App Store score, 4.3 against 4.0. That said, the two scores are not equally well evidenced: uDisk has 233 ratings behind it against 9, so its average is the more settled of the two. Written reviews point the same way: 84% of uDisk's written reviews are positive against 64% of U8's.

uDisk ships an update every 2 months, U8 every 6 weeks. Both last shipped on September 17, 2026.
