# USB Sharp vs iTransfer

The clearest difference is rating: iTransfer at 4.1 against USB Sharp's 3.1. iTransfer also leads on ratings volume (214 vs 18). USB Sharp's advantage is update cadence (every 3 weeks vs every 4 months) and iOS requirement (13.0 vs 15.0). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. USB Sharp sells 6 one-off in-app purchases and iTransfer sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

iTransfer holds the better App Store score, 4.1 against 3.1. That said, the two scores are not equally well evidenced: iTransfer has 214 ratings behind it against 18, so its average is the more settled of the two. Written reviews complicate that: 53% of USB Sharp's written reviews are positive against 52% of iTransfer's, so the app with the better star average is not the one people write more warmly about.

USB Sharp ships an update every 3 weeks, iTransfer every 4 months. The most recent releases landed on September 21, 2026 and September 29, 2026 respectively.
