Ratings and reviews

simple and quick to use. No clutter. Can do scripting. If it could do automatic very basic JSON string key value parsing and just display this on a dash (no frills) it would be even better. Perhaps it can through the scripting feature, but I am not there yet 😬

Great app, great developer. I was using another MQTT client app with Tasker plugins, which is no longer maintained and has become unreliable. I was really happy to discover this app but was a little disappointed that it didn't support self-signed cetificates. I emailed the dev to ask if there were any plans to support this, and it was added in the next update the following day! Everything is working flawlessly now, and I really can't recommend this app enough.

Rarely are there times when I wish I could give more than 5 stars. This is one! Very responsive dev - highly open to ideas and dedicated to quality. So I suspect any issue you might find will be rapidly addressed once reported. I bought PRO to get scripting and more! Well worth it. I am not sure why they feel they must have a completely different app for tablets. This seems to work just fine on a phone in landscape mode and on Android x86 in a virtualbox - which is landscape natively. Thanks!
