# MQTT vs IoT

The clearest difference is price: MQTT at Free against IoT's $0.99. MQTT also leads on iOS requirement (15.0 vs 17.6). On ads, in-app purchases and device support there is nothing between them.

MQTT is free to download; IoT costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.
