This is an MQTT client and test tool. MQTT is a machine-to-machine (M2M) messaging protocol commonly used for IoT applications. For more information on MQTT visit http://mqtt.org MQTTool can connect to authenticated and unauthenticated MQTT brokers, subscribe to topics, and publish messages to topics. I built this tool as i was doing my own MQTT investigations and I've posted it hoping others would find it useful too. I continue to use it on projects, and I'm continuing to look to improve this tool. If there are changes that would make this more useful, please send me feedback. Thanks!

The app has a control range with the ability to control between zero and five lights and doors, depending on the use case. By means of a red-green indicator, the user is shown the connection status of the server. In the settings area of the app the server connection details can be entered. Depending on the use case, the controls for the lights or doors can be switched on and off. For the individual lights and doors, the corresponding theme as well as the message can be set. In addition, further settings for the transmission can be selected.

The clearest difference is update cadence: MQTTool at every 4 weeks against MQTT's every 11 months. MQTTool also leads on iOS requirement (10.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.
