# USB Sharp Pro vs Disk Mounter Professional

The clearest difference is rating: USB Sharp Pro at 4.0 against Disk Mounter Professional's 3.0. USB Sharp Pro also leads on ratings volume (12 vs 2). Disk Mounter Professional's advantage is review sentiment (80% vs 60%) and update cadence (monthly vs every 2 months). On ads, in-app purchases, monetization model and device support there is nothing between them.

USB Sharp Pro costs $2.99 and Disk Mounter Professional $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

USB Sharp Pro holds the better App Store score, 4.0 against 3.0. That said, the two scores are not equally well evidenced: USB Sharp Pro has 12 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 60% of USB Sharp Pro's written reviews are positive against 80% of Disk Mounter Professional's, so the app with the better star average is not the one people write more warmly about.

USB Sharp Pro ships an update every 2 months, Disk Mounter Professional monthly. The most recent releases landed on September 22, 2026 and September 19, 2026 respectively.
