Verdict
The clearest difference is rating: Thunder Scanner at 4.7 against USB's 4.2. Thunder Scanner also leads on ratings volume (649 vs 16) and update cadence (every 2 weeks vs monthly). USB's advantage is in-app purchases (none vs 3) and ads (none vs shown). On price, review sentiment, device support and iOS requirement there is nothing between them.

Both are free to download. Thunder Scanner sells 3 in-app purchases, starting at $2.99 per 7 days. USB asks for nothing beyond the download.
Thunder Scanner holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: Thunder Scanner has 649 ratings behind it against 16, so its average is the more settled of the two. Written reviews complicate that: 75% of USB's written reviews are positive against 71% of Thunder Scanner's, so the app with the better star average is not the one people write more warmly about.
USB ships an update monthly, Thunder Scanner every 2 weeks. The most recent releases landed on October 10, 2026 and October 8, 2026 respectively.
