# USB Sharp vs uDisk

The clearest difference is rating: uDisk at 4.3 against USB Sharp's 3.1. uDisk also leads on ads (none vs shown) and review sentiment (84% vs 53%). USB Sharp's advantage is update cadence (every 3 weeks vs every 2 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. USB Sharp sells 6 one-off in-app purchases and uDisk 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 3.1. That said, the two scores are not equally well evidenced: uDisk has 233 ratings behind it against 18, so its average is the more settled of the two. Written reviews point the same way: 53% of USB Sharp's written reviews are positive against 84% of uDisk's.

USB Sharp ships an update every 3 weeks, uDisk every 2 months. The most recent releases landed on September 21, 2026 and September 17, 2026 respectively.
