MQTT client app

### 4/5 — A very good MQTT client

*2020-01-24*

I'm using this to monitor a couple of IoT projects output snd it works very well. I like the topic editing feature - in many similar apps you have to delete and reenter the whole topic string, but sensible editing options make this app better. Would it be possible to add a monospace font option? 

Overall though, a very good app.

**Developer response:** Thank You for your valuable feedback, In current app there is already available a topic editing features for this you have to just a long press on topic and it goes for editing. 
And in future we will try to add a support for monospace font.

### 4/5 — New to MQTT

*2019-12-16*

I have just started using MQTT protocol with Mosquitto Broker on my Raspberry pi. This app works great whilst testing that your devices are communicating correctly and is easy to set up and use.

**Developer response:** Thank You for your valuable feedback.
