# uDisk vs i

The clearest difference is review sentiment: uDisk at 84% against i's 20%. uDisk also leads on rating (4.3 vs 3.0) and ratings volume (233 vs 2). i's advantage is in-app purchases (none vs 1) and iOS requirement (8.0 vs 11.0). On price, update cadence, ads and device support there is nothing between them.

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

uDisk holds the better App Store score, 4.3 against 3.0. That said, the two scores are not equally well evidenced: uDisk has 233 ratings behind it against 2, 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 20% of i's.
