At last! A good MQTT client app!
I've tried a few MQTT clients over the last year or so and most of them work, but the layout and execution is poor. This app seems to have been designed by people that actually use their own software and it works really well, so thanks for that. The UX is good also. What I particularly like is the ability to mark messages read and also clear them: this wins a major battle with clutter! It connects to my MQTT server without problems. The only slight nibble is that I can't remove the 2 preset entries, but other than this it just works.
