# IoT USB vs QR Vision

The clearest difference is in-app purchases: IoT USB at none against QR Vision's 1. IoT USB also leads on ads (none vs shown) and iOS requirement (9.0 vs 17.0). On price and device support there is nothing between them.

Both are free to download. QR Vision sells 1 in-app purchase, starting at $2.49 per month. IoT USB asks for nothing beyond the download.
