# FastCast. vs iUSB

The clearest difference is rating: FastCast. at 3.8 against iUSB's 2.8. FastCast. also leads on ratings volume (282 vs 24). iUSB's advantage is in-app purchases (none vs 3) and ads (none vs shown). On price, review sentiment and device support there is nothing between them.

Both are free to download. FastCast. sells 3 in-app purchases, starting at $0.99 per 7 days. iUSB asks for nothing beyond the download.

FastCast. holds the better App Store score, 3.8 against 2.8. That said, the two scores are not equally well evidenced: FastCast. has 282 ratings behind it against 24, so its average is the more settled of the two. Written reviews complicate that: 21% of FastCast.'s written reviews are positive against 25% of iUSB's, so the app with the better star average is not the one people write more warmly about.

FastCast. ships an update every 2 months, iUSB every 10 days. The most recent releases landed on September 21, 2026 and September 22, 2026 respectively.
