I use this all the time to monitor numerous topics/messages on my broker backbone. I use MQTT messages to monitor 6 different solar battery systems, 2 water tanks, thermal sensors, etc. Many of these messages are parsed and put in a MariaDB, but some are just sent to the broker so having a good client that lets me watch them as needed is a real help. Only issue I have is that when switching between apps I get disconnected from the server too often. Some of the messages are only posted every 5 or 10 minutes, so I wish I didn't have to just sit with this app in the foreground all the time so I don't miss messages. Other than that, great tool!

This tool is an excellent mobile substitute for the MQTT Explorer desktop app. It’s simple, flexible, and straightforward. I like that it’s open source, so I can learn from it and someday maybe write my own app!

I am developing a containerized app to periodically poll EDS MeshNet environmental sensors via HTPP on my LAN and publish the data to Mosquitto MQTT for discovery and use within Home Assistant. I have been using MQTT explorer on windows for debugging but this is the best app I’ve seen for iOS. Nice work!
