# Discount Calculator vs QR code

The clearest difference is ads: Discount Calculator at none against QR code's shown. Discount Calculator also leads on update cadence (every 3 weeks vs every 3 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Discount Calculator ships an update every 3 weeks, QR code every 3 months. Both last shipped on October 27, 2026.
