# uDisk vs USB Fusion

The clearest difference is rating: USB Fusion at 5.0 against uDisk's 4.3. USB Fusion also leads on in-app purchases (none vs 1) and review sentiment (100% vs 84%). uDisk's advantage is ratings volume (247 vs 1) and device support (3 vs 1). On price, update cadence, ads and iOS requirement there is nothing between them.

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

USB Fusion holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: uDisk has 247 ratings behind it against 1, 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 100% of USB Fusion's.
