Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

USB ships an update monthly, Thunder Scanner every 2 weeks. The most recent releases landed on October 10, 2026 and October 8, 2026 respectively.
