# iUSB Pro vs Aidisk

The clearest difference is rating: Aidisk at 3.0 against iUSB Pro's 2.6. iUSB Pro's advantage is ratings volume (1.1K vs 1). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Aidisk holds the better App Store score, 3.0 against 2.6. That said, the two scores are not equally well evidenced: iUSB Pro has 1.1K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 14% of iUSB Pro's written reviews are positive against 9% of Aidisk's, so the app with the better star average is not the one people write more warmly about.

iUSB Pro ships an update every 3 months, Aidisk every 6 weeks. The most recent releases landed on October 16, 2026 and October 7, 2026 respectively.
