The idea is to have a monitor app with which you can connect to an MQTT broker, subscribe to a number of topics and publish a text payload to a topic or two for debugging purposes.

The result is a pretty versatile utility for your MQTT toolchest. It serves as a viewer with which you can observe payloads being published to topics you're interested in, and you can publish payloads to topics at the tap of a button. The app is designed to work on both iPad and iPhone.

Really useful.

This is a great utility for monitoring and injecting info via MQTT. I have been using it to help me integrate my Pycom LoPy4 devices into my Home Assistant based smart home.
My only suggestion for an improvement would be to enable the user to select a larger font when viewing the message content with the Info button, as this always seems a bit too small for me.
Definitely worthy of 5 stars.

Very useful app

Good with some useful features

Totally unintuitive but finally worked out how to use the app. Has some very useful features such as multiple concurrent subscriptions. Other similar tools are limited to one subscription at a time.
Would benefit greatly from having some instructions.
