# uDisk vs i

The clearest difference is review sentiment: uDisk at 84% against i's 15%. uDisk also leads on rating (4.3 vs 2.8) and ratings volume (233 vs 23). i's advantage is in-app purchases (none vs 1). 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 2.8. That said, the two scores are not equally well evidenced: uDisk has 233 ratings behind it against 23, 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 15% of i's.

uDisk ships an update every 2 months, i every 5 weeks. The most recent releases landed on September 17, 2026 and September 20, 2026 respectively.
