However, after an upgrade from iPhone 7 to 16, I find it is near impossible to navigate within the app anymore. Various icons for navigation do not respond to touch. ### 2/5 — Poor support for an iPhone 14+ *2024-04-03, version 4.0.2* Pity, had promise but has an interface that: 1) forces iPhone 14+ users to keep tapping around commands until luck is on their side to execute them; and 2) leaves iPhone 14+ users to wonder what’s displayed under the island the app clearly knows nothing about. Very frustrating. Too bad. ### 2/5 — Graph widget updated only when app in foreground *2023-09-27, version 4.0.2* The graph widgets cannot handle an array of values or updated while the app is in background. In this way it is not possible to see, for example, the history of the temperature of a room. ### 2/5 — Difficult to tap *2023-09-17, version 4.0.2* Menu buttons too close to corners, really hard to tap on Iphone 14. Using this app is really frustrating experience. GUI definitely needs redesigning. ### 3/5 — Still supported? *2023-07-13, version 4.0.2* Is this app still supported? I wrote the author almost three weeks ago and I'm still waiting for an answer. I bought the backup feature and I want to know where are the backups stored. ### 4/5 — Almost perfect *2023-05-03, version 4.0.2* The app is almost great. However, for JSON that uses the underscore character, result is always unknown. Thus any JSON using underscore is unusable. I can enter dot notation like DS18B20.Temperature and data is received correctly. However, if the sensor is DS_18B20.Temperature, the app throws an error and no value is returned. ### 3/5 — Need improvement *2022-03-06, version 4.0.2* It's good but doesn't work fine on latest ios 15 ### 3/5 — Виджеты *2021-08-07, version 4.0.2* Сделайте виджет с возможность выбора количества включателей от 1 до 5 и подписи их названий. Будет ли русский язык? Могу помочь с переводом на русский!!! ### 4/5 — Doesn't answer questions *2021-05-08, version 4.0.2* I sent email to support but didn't got answer. The app is very good but although I see family sharing enabled, it doesn't work. I want to share my configuration on the different family devices but it doesn't work. Seems I need to pay for every family member this app? ### 2/5 — Top bottom controls don’t work on iPhone 12 mini *2021-01-31, version 4.0.2* Have to hit the controls 10 times to activate. I will abandon this otherwise great looking appp ### 3/5 — Geht so *2021-01-19, version 4.0.2* Positiv: Man kann MQTT mit TLS zu einem eigenen Server nutzen, das klappt auch ganz passabel. Negativ: Es gibt nur eine handvoll Widgets und nicht jedes ist sinnvoll. Vor allem der Graph erlaubt zwar lange Zeiträume, aber um das Darstellen zu können müsste man die App aktiv halten und das Telefon am Standby hindern; im Hintergrund füllen sich Graphen nicht weiter. Entweder kann man numerische Werte oder Zeichenketten als Wert nutzen. Man kann einen JSON Parser dazu buchen, der kann aber auch nur einzelne Felder herausfiltern. Formeln, Stringverkettungen oder ähnliches gibt es nicht - das ist nicht flexibel. Google Analytics ist leider auch mit drin und der Entwickler hält auch daran fest dass das eine gute Sache ist - ja sogar als professionelle Softwareentwicklung zu sehen sei. Eine Option Tracking in der Premium Variante zu deaktivieren wurde vor zwei Jahren in Aussicht gestellt, aber nie umgesetzt. Statt dessen wurde nur die Datenschutzerklärung erweitert und somit jegliche Hoffnung auf Einlenken zunichte gemacht. Fazit: Erstmal nutzbar, aber ich hoffe auf Alternativen. Von den In-App Käufen lohnt es sich nur die Widgetbeschränkung aufzuheben. Der JSON Parser und die Backupfunktion sind das Geld nicht wert. ### 4/5 — SHORTCUTS NEEDED *2021-01-17, version 4.0.2* Guys, we beg you! Please! Add shortcuts, so we could control everything through voice commands. Everything else, stable and good. ### 4/5 — Owesone App but need one help on issue *2020-12-25* Good application best for developer and end user I used many time worked well since 24 dec it’s crashing on my iOS 14.3 when trying to connect to broker Kindly suggest way to handle it .. ### 4/5 — Bitte Updaten! *2020-12-09, version 4.0.2* Lässt sich nicht komplett mit den 12er iPhones bedienen. Wäre sehr schade, wenn das nicht angepasst wird. Nachtrag: Wenn man etwas von unten an die Buttons (Edit, Done usw.) "ranwischt", dann gehts. Ist aber nicht perfekt. ### 4/5 — Very useful.....but no datalogger included *2020-11-06, version 4.0.2* I use this App for roundabout 1 year (mosquitto + local raspberry) and think it‘s ... + very useful for prototyping , debugging + quick and beautiful gui But i urgently miss a datalogger-widget and easy export to excel or csv-format or somthing like that... ## Most critical reviews (10 lowest-rated) ### 1/5 — Não funciona com versão 18.5 *2025-10-21, version 4.0.2* Ruim. Os ícones às vezes funcionam, na maioria das vezes não. Instável. Testei num outro celular antigo com outro ios antigo e foi bem. ### 1/5 — No longer seems to work in iOS18 *2025-08-21, version 4.0.2* Trying to setup again on a new iPhone 14, and it just either does not respond to screen clicks like Add or Back etc. can add a group name on first page, but no way to save it or add items. I have the extra ‘Storage Manager’ but it does not see saved configs, even with correct ‘Share’ code entered. ### 1/5 — Restore data not work *2023-11-03, version 4.0.2* All of app it is ok. but the restore data not found after remove and reinstall program. my all mqtt dashboard missing very waste the time for new config. ### 1/5 — Is this really functional anymore *2023-06-28, version 4.0.2* Looks a lot of work went into it but the UI on a modern iPhone is very frustrating. I have been trying to configure it with a hivemq server and finally seems to be connecting but for the life of me I cannot configure widgets to my topics. The interface & buttons don’t seem to follow standard Apple conventions and can’t find documentation. ### 1/5 — Проблемы с откликом *2022-02-16, version 4.0.2* Очень сильно тупит на нажатие, ощущение что тачскрин не работает ### 1/5 — Frustrating *2022-02-09, version 4.0.2* Could be a great app. But possibly the most frustrating app I’ve ever used! “Ready” button so close to the top of the screen you can’t tap it. App regularly locks up for no reason ### 1/5 — Auf iPhone 12 Pro Max fast nicht benutzbar *2021-02-13, version 4.0.2* Das Userinterface ist auf dem iPhone 12 Pro Max fast unbrauchbar. Mit meinem iPhone 8 war die App gut bedienbar. Aber jetzt sind Buttons alle extrem weit in den runden Ecken und dadurch nur schwer bis gar nicht erreichbar. Das muss unbedingt geändert werden! Ich vermute, dass es bei älteren Modellen das Gleiche ist. ### 1/5 — Keine Anpassung an iPhone X *2021-02-08, version 4.0.2* Seit ich auf ein neues iPhone gewechselt bin, ist das Programm kaum mehr zu bedienen, da die Programm-Buttons so am Rand sitzen, dass man manchmal 10 mal tippen muss um den Button zu treffen. ### 1/5 — Не конектится с CloudMQTT.com *2019-10-13, version 3.05.06* Замучился уже, не получается законектить ### 1/5 — Not work good *2019-08-21, version 3.05.06* I coneccted in the cloudmqtt.com and I get publish there but when I’ll subscribe the message of my esp32 send with THE SAME TOPIC, um the app they don’t get the message ## Most praised reviews (10 highest-rated) ### 5/5 — IOT On/Off *2024-02-17, version 4.0.2* It took some effort on my part to get the code to compile for Arduino using MQTT. But can confirm this App works nicely using MQTT to see temperature data. The widgets are clean looking and clearly show the data. ### 5/5 — Great app *2023-05-19, version 4.0.2* It’s all well dome, I’m using this app. Is it possibile to have also big colored buttons like switch? ### 5/5 — Configurable Interface *2022-12-20, version 4.0.2* Connected just fine to my Ubuntu server running Mosquitto. ### 5/5 — Smart MQTT that works *2021-07-06, version 4.0.2* Great app with cool UI ux that just works. I use it to setup dashboard for my esp32 based sensors and relays. MQTT broker installed on the local raspberry pi. Works very well! ### 5/5 — Расширение функционала *2021-04-05, version 4.0.2* Очень хорошее приложение. Разработчики, добавьте возможность вычитывать нужный бит из данных. Используем приложение как диспетчерский пункт для промышленных объектов. Отсутствие выборки бита мешает полноценному использованию. Если добавите это, обеспечу много клиентов и покупок в приложении, так как используем существующий функционал по полной. Выйдите на связь. Есть деловое предложение) ### 5/5 — Ótimo para MQTT *2021-03-28, version 4.0.2* Ótimo app!! Parabéns! ### 5/5 — great app *2021-01-13, version 4.0.2* Thanks a lot for this wonderful utility! It works like a charm with my local mosquitto broker. The full import/export function makes it possible to edit json structure directly that is so valuable during initial setup with multiple panels and widgets. The only thing I am missing now is the pushbutton widget, switch is not suitable in some applications. Could you please include the pushbutton in some of your future releases? Just a button that sends the defined value. Thanks a lot for your effort! ### 5/5 — Arduino + Synology + Mosqitto *2020-10-25, version 4.0.2* Единственный брокер который смог толком подключит в такой связке. Работает стабильно без нариканий. Разработчикам спасибо, хотелось бы побольше красочных виджитов ### 5/5 — Cool *2020-05-24, version 4.0.2* The only app that works ### 5/5 — The best that I find for IOS *2020-05-11, version 4.0.2* Works very well --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
