# HS vs SmartScanner

The clearest difference is review sentiment: SmartScanner at 40% against HS's 0%. SmartScanner also leads on ratings volume (1.2K vs 1) and iOS requirement (15.0 vs 17.6). HS's advantage is in-app purchases (none vs 10) and rating (5.0 vs 4.7). On price, ads and device support there is nothing between them.

Both are free to download. SmartScanner sells 10 in-app purchases, starting at $0.99 per month. HS asks for nothing beyond the download.

HS holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: SmartScanner has 1.2K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of HS's written reviews are positive against 40% of SmartScanner's, so the app with the better star average is not the one people write more warmly about.

HS ships an update every 3 weeks, SmartScanner every 2 months. The most recent releases landed on November 3, 2026 and November 7, 2026 respectively.
