# QR code vs Discount Deal Calculator

The clearest difference is ads: Discount Deal Calculator at none against QR code's shown. QR code's advantage is update cadence (every 3 months vs every 10 months) and iOS requirement (13.0 vs 17.6). On price, in-app purchases and device support there is nothing between them.

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

QR code ships an update every 3 months, Discount Deal Calculator every 10 months. The most recent releases landed on November 7, 2026 and October 30, 2026 respectively.
