Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
GWSCAN holds the better App Store score, 4.3 against 2.8. That said, the two scores are not equally well evidenced: GWSCAN has 83 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 100% of BLAZER WMS's written reviews are positive against 68% of GWSCAN's, so the app with the better star average is not the one people write more warmly about.
BLAZER WMS ships an update every 2 weeks, GWSCAN every 2 months. The most recent releases landed on October 4, 2026 and October 18, 2026 respectively.
