After the measurement without any problems, the application encounters a problem when I want to see the data. ### 2/5 — Can’t export my recorded data file *2023-09-26* The app often crashes when I’m trying to export my recorded data .. unreal.. not to mention sometimes it will stop measuring second by second and start measuring every 2 seconds 3 seconds etc which means I miss important data.. I like that it mirrors the device on my phone but the app has some serious bugs.. record your data but can even export it .. ### 1/5 — Cuidado borra base de datos *2023-03-15* Al actualizar borra la base de datos previa de todos los estudios y no veo manera de recuperarlo ### 2/5 — Schlechte Bedienbarkeit *2022-08-23, version 2.3.1* Leider ist es sehr schwierig, die Sprache der App umzustellen. Wenigstens auf Englisch auszuliefern, wäre doch schon hilfreich. Der Hinweis auf den „dritten Eintrag von unten“ war letztendlich zielführend, wenngleich die Anzahl der Menüeinträge bei verbundenen Geräten sich ändert. Arg hinderlich ist jedoch die absolut mangelhafte Reaktion des Menüs auf Fingerbedienung. Mit viel Glück wird tatsächlich eine Funktion ausgelöst, die nicht einfach nur das Menü wieder schließt. Und so ist es dann mit viel Geduld und unzähligen Anläufen gelungen, mit dem dritten Eintrag von unten einen Dialog aufzurufen und darin Englisch als Sprache einzustellen. Hosianna! Das Einstellen der Meta-Informationen für die PDF-Dokumente ist noch immer nicht abgeschlossen. Irgendwann gelang einmal der Aufruf der entsprechenden Felder. Seitdem jedoch nicht mehr. :( ### 2/5 — Нет даже английского языка *2022-01-06, version 2.2.0* Приложение норм. Но только Упрощенный китайский. Нет даже английского. ### 1/5 — Schlecht. In chinesisch, kombiniert mit englisch. *2021-03-27, version 2.0* — ### 1/5 — iOS Developer *2020-10-25, version 1.3* Очень сырое приложение. Многие функции есть, но не работают. ### 2/5 — Disappointing. Does not work well at all. *2020-08-09* Although the app appears to work at first glance, dialogs are dismissed before the user has a chance to do anything. As an example, trying to change the upper threshold for an alarm is next to impossible. Even when the threshold is exceeded, no alarm sounds. Sadly, this app is just too buggy to be useful. ### 1/5 — Bad *2019-06-05, version 1.3* Display on iPhone 7 doesn’t reveal all items under settings Frequent hang ups with export email ### 3/5 — Halfway there.... *2019-04-06* They seem to have fixed the Chinese-only bug, but haven’t loaded any English translations. So, all the buttons look like variable names. App seems to work otherwise. Using with a UT383 BT light meter, which by itself is awesome. If they improve this app so I can robustly log the data, this becomes five stars for me. ### 1/5 — Need more *2019-03-06, version 1.3* Need average values And need separate data in cell excel ## Most critical reviews (10 lowest-rated) ### 1/5 — Repeated Review Attempts Fail *2026-05-30* I have tried to post my review with a complete list of all of the many bugs in this program and every time I do, the review never shows up. I am a software engineer and I would think the people who write this program would be interested in seeing the list of bugs and how to reproduce them. There are so many as to make the program essentially useless. But my reviews never post. And there is no way to contact them directly because if you click the "app support" button it takes you to their website… Which doesn't exist. There is literally no way to contact these people. ### 1/5 — Not efficient for lux *2026-02-04, version 2.7.6* Is not possible register isolated value in manual, register only in automatic with sample… ### 1/5 — Kapanıyor. *2025-04-24, version 2.6.3* Kayıt almak istediğimde program kapanıyor.. ### 1/5 — Padani aplikace *2025-04-10, version 2.6.3* Pri zapnuti a sparovani pristroje a zapnuti mereni rpm se aplikace restartuje a pristroj odpoji. ### 1/5 — Essentially it works *2024-11-13, version 2.6.0* It works as remote display while crashes when I press record trying to gather continuous graph. And there’s no Windows app. Would be 3 at this point but still 1 for deleting feedback. ### 1/5 — No graphs, crash app *2024-07-06, version 2.6.0* App crash’s at record command No graphs are displayed ### 1/5 — Not working with IOS device *2024-05-09, version 2.6.0* When you want to measure speed of motor, application is closing immediately. It is connecting to device without any problem but when data transfer starts, application closing. ### 1/5 — Crash no app para descarregar os dados *2023-09-14* O aplicativo está dando crash ao tentar exportar os dados. Ele simplesmente fecha ### 1/5 — In chinese only *2023-07-09, version 2.3.2* On my IP 14 pro, the app is default in chinese and can’t switch to english, it turns back to chinese. Useless. ### 1/5 — Working good before my new Db meter *2023-04-15, version 2.3.2* App is nice visualy and working good with my anemometer + recording stats but… Now i have Db meter and when i start recoding app crash everytime after 2-3 sec. And in this 2-3 seconds reading numbers from device , but graph are clean Can you fix it please Thank you After fix i change my stars cuz app is good and i want use it ## Most praised reviews (10 highest-rated) ### 5/5 — Ut336p *2025-10-01, version 2.6.8* Now it work ! Thank you ### 5/5 — Works great! *2023-01-21* Fixed the bug. Can read in English now. ### 5/5 — Good if… *2022-02-09, version 2.2.0* it will be great if the application has the ability to calculate the air flow in the duct, round or square, using an anemometer! ### 5/5 — Great *2018-12-22* Great and easy to use. Has awesome recording and export features generating easy to read graphs. ### 4/5 — Device does not appear in the App *2021-06-08, version 2.0* Dear Developer Team. Unfortunately, the UT353 BT does not show up at all in the app. Every possible combination of Bluetooth on/off has been tried. Any suggestions? Thanks. Alex. ### 4/5 — Nur in Chinesisch ? *2021-04-17, version 2.0* Also die App ist funktionell, die Verbindung blitzschnell eingerichtet. Allerdings sind alle Menüs in Chinesisch, oder ich stelle mich zu blöd an..... Chinesisch ist halt nicht gerade meine Kernkompetenz 🙈 Nachtrag, habe es gefunden. Im Pulldown-Menü ist es der dritte Punkt von unten, dort kann man Englisch einstellen, und dann sind alle Menüs in Englisch. 👍 ### 4/5 — Please update App for new iPhones *2020-12-03* The App concept is OK but one remark, is impossible use the back navigation button < in the iPhone X (on top left on the some screens). The App needs a little update for the iPhone X or others. Will be welcome a new version. Many thanks. ### 4/5 — Appli fonctionnelle *2019-06-26* Bonne application qui Reçois bien en temps réel les données de la mesure par le Bluetooth. Pas de problème de détection des équipements, cela est bien pris en charge. Par contre lors de l’enregistrement des data, l’export qui est fait sous forme graphique en format png ou PDF, il y a un bug sur l’axe x du temps , la date qui apparaît est toujours la même, au lieu d’évoluer avec la valeur des données échantillonnés. Sinon bien. ### 3/5 — I can not export my data *2023-08-01, version 2.3.2* I measured the wind a few minutes ago without a problem. I saved to a file. I used a different file name. Later when I wanted to export the file the application stops without notice and the device disconnects. I use an iphone device with ios 15. I will try one more time but this time with macbook. Can you please check what may be the cause of this problem. ### 3/5 — UT353BT Aufzeichnung Failure *2023-05-03, version 2.3.2* Datenaufzeichnung mit dem Sound Meter funktioniert nicht. Sobald erster Meßwert übertragen wird, stürzt APP ab. Mit dem UT333BT (Wind Meter) funktioniert es einwandfrei. Möchte mir noch mehr Geräte kaufen, aber nun bin ich skeptisch und warte auf das nächste Release. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
