# MQTTAnalyzer vs IoT EMS

The clearest difference is update cadence: MQTTAnalyzer at every 5 days against IoT EMS's every 2 months. IoT EMS's advantage is iOS requirement (13 vs 18.0). On price, ads, 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.

MQTTAnalyzer ships an update every 5 days, IoT EMS every 2 months. The most recent releases landed on September 21, 2026 and September 17, 2026 respectively.
