### 4/5 — Cool but...

*2019-11-20, version 2.6*

Cool useful app. However, I wish there was a way to use Siri with it.

### 4/5 — Handy utility, although UI a bit confusing

*2019-08-13, version 2.6*

I was spending a but of time checking my mqtt broker until I finally realized I need to tap on the “connect” text in the main window instead of the “connect” icon at the bottom left of the screen 😳

Once that was sorted out the app works nicely 👍

### 5/5 — Perfekt small Tool

*2019-03-07*

Einfaches schlankes Tool das genau das hält was es verspricht!
Keine nervige Werbung, keine undurchsichtige Bedienung
Wer schlechte Bewertungen abgibt wegen fehlender TLS Unterstützung der sollte lesen lernen, das wird nirgendwo versprochen.
Es müsste mehr so einfache Apps geben welche genau das machen was sie versprechen
DANKE

### 5/5 — Mqtt newbie

*2019-02-02, version 2.5*

Brilliant and simple. All that is needed and no more. Works exactly as expected. Very nice work

### 5/5 — Nothing to complain about

*2019-01-30*

The MQTT tool works flawlessly. Thanks to the developer for sharing.

### 4/5 — Bonne appli

*2019-01-16*

Une appli sobre mais efficace pour
Tester mqtt

### 5/5 — Great Tool

*2019-01-04, version 2.5*

Need to test a MQTT server on your LAN?  This fits the bill. I was setting up a server for home automation and this app provided a means for testing my setup.

### 5/5 — Einfach und gut

*2018-12-27*

zum Überwachen meiner IoT Sensoren brauchte ich einen einfachen MQTT Subscriber und dieser hier war genau der Richtige.

### 5/5 — Does the job

*2018-11-24, version 2.5*

I was looking for an iOS client to use for my Arduino experiments. I was able to interact with my Arduino device within 10 minutes of downloading this app. Very handy.

### 5/5 — Works as described!

*2018-09-02*

Handy tool for monitoring MQTT payloads while testing devices. Subscribe to # to see all messages from your devices and just set up a broker user ID with read access only for use with this software, add write access if you need it later

### 5/5 — Does what it needs to

*2018-05-30, version 2.4*

Simple app that does what it needs to. Very useful when setting up or making new diy  devices!

### 5/5 — Great tool

*2018-02-05, version 1.50*

This is a very simple tool, which does what it’s supposed to do. Indispensable in my development!

### 1/5 — wont allow me to enter subscription

*2024-01-14, version 2.6*

does not open virtual keyboard when touching the field on iphone

### 1/5 — Couldn’t get it work

*2022-11-09, version 2.6*

Couldn’t get it to work. Bummer huh?

### 1/5 — Leider unbrauchbar

*2020-04-26*

Kann mich nicht per ip mit meinem Server verbinden und daher ist es für mich unbrauchbar.

### 1/5 — Unable to connect to server

*2020-03-25, version 2.6*

It won’t connect to my server. I am using the same credentials and settings as I use in an app on my laptop. Just won’t connect

### 1/5 — Unusable

*2019-04-10*

Cannot type in "topic" field

### 1/5 — Не подключается к брокеру

*2018-10-05*

Не подключается к брокеру. Постоянно теряет связь.

### 1/5 — No current TLS

*2018-02-03*

Sadly this client is wide range out of time and does not support state of the art SSL protocols.

### 2/5 — Keyboard prevents screenchange

*2018-02-17*

I cannot click on tab subscribe or other as the keyboard always is up and never disappears, so I simply cannot reach the other tabs 😕. Please fix this.

### 3/5 — Does Need More Work

*2017-02-26, version 1.20*

A nice tidy app visually, but for a paid app it needs more work.  You cannot publish or subscribe multiple channels successfully and the app just seems to stop if you put it into background after a while.  This means you cannot catch-up on subscription data if you move the app out of foreground.

### 4/5 — Sehr nützlich und schlank ohne Werbung

*2020-08-29*

Muss leider einen Stern abziehen, da die Funktionen Save Password nicht korrekt funktioniert. Bei jedem Neustart der App muss man den Haken wieder erneut setzen.
Vergisst man das, ist das Passwortfeld beim nächsten Start leer.

The Save Password function does not work correctly. Each time you restart the app you have to tick the box again.
If you forget that, the password field will be empty the next time you start.

### 5/5 — Very nice simple app

*2025-06-25, version 2.6*

I was able to connect to my local ESP32 server, subscribe to topics and publish on topics.

The interface is very intuitive.

I would suggest one improvement - option to publish in JSON format.

I published a message in JSON format but it was not recognized by the server.

It would be great to add JSON format.

I commend you for this very nice app !!!

Thanks :)

### 5/5 — Top

*2023-07-06*

Ein sauber programmiertes Tool zum Testen von MQTT Projekten.

### 5/5 — Очень неплохо

*2022-10-23*

Для теста сервера очень удобное приложение. Спасибо разработчикам.

### 5/5 — Exactly the Right Tool!

*2021-09-05, version 2.6*

I’m just starting to understand the MQTT side of smart devices and this app I had connected and sending & receiving on all first attempts. Very user friendly!

### 5/5 — Отлично

*2020-01-09*

Делайте больше фич и платную версию!

### 5/5 — Works great.

*2020-01-02, version 2.6*

You need to push on the text in the body of the page for both “connect” and “publish” rather than below on the menu bar. These could be highlighted or a different color and In bold to make it a little nicer. But it works great! I tried it for publishing and subscribing to a Mosquitto MQTT broker on a Raspberry Pi and had no troubles. Great app.

### 5/5 — Sencilla pero muy útil

*2019-12-22*

Esta aplicación es muy sencilla de manejar y a la vez muy útil a la hora de testear nuestras redes Mqtt.

### 5/5 — good and easy to use

*2019-06-13, version 2.6*

simple but works great for me

### 5/5 — More function needed

*2019-04-11, version 2.6*

Thanks for developing this app. Very handy. Is it possible add more function, such as sub multiple subjects and pub automatically

### 5/5 — perfect

*2019-04-10, version 2.6*

Exactly what I needed to talk to some esp8266 MQTT nodes I am developing. Works well, saved me the trouble of handling ios myself. Many thanks.
