# QR Code vs SeeChanges AI

The clearest difference is ads: SeeChanges AI at none against QR Code's shown. SeeChanges AI also leads on update cadence (every 2 days vs every 14 months). QR Code's advantage is iOS requirement (11.1 vs 16). On price, in-app purchases and device support there is nothing between them.

Both are free to download. QR Code sells 1 in-app purchase, starting at $4.99 per 7 days and SeeChanges AI sells 10 in-app purchases, starting at $3.99 per 3 months. Whichever you choose, the download price is not the number that matters.

QR Code ships an update every 14 months, SeeChanges AI every 2 days. Both last shipped on September 30, 2026.
