*2019-01-28, version 1.5.1*

Здравствуйте. В наличии прибор testo 330 2LL  ПО v2.20 (функция Bluetooth есть), телефон на базе Андройд связывается, а iOS не обнаруживает газоанализатор.

### 1/5 — Horrible APP

*2018-12-22*

### 1/5 — No connection

### 1/5 — Garbage

*2018-10-07*

I just spent $1,300 on a new 320 lx kit and it won’t connect to my iPhone. So if I want Bluetooth I have to go get another phone line?

### 1/5 — Doesn’t connect

*2018-09-09*

Bought a brand new 320 LX looking forward to using this app just to find out this app won’t connect to it.  Hope they fix this, as it was a selling point.

### 1/5 — Applicazione non professionale

*2018-07-24, version 1.5.1*

Si blocca continuamente, dovrebbe essere ampliata a tutte le funzioni dello strumento testo 330 1x con tutti i tipi di misura che lo strumento è in grado di eseguire. Inoltre la misura deve rimanere in memoria anche se spengo lo strumento.

### 1/5 — Can’t connect Bluetooth

*2018-06-04*

I can’t detect 330-2LL...

### 1/5 — App funktioniert ABER!

*2018-05-02*

Eingabe von Kundendaten über Smartphone/Tablet bisher nicht möglich.
Anzeige der BimSch-Messung auf Mobilgeräten nicht möglich.
Übernahme der Messwerte in Handwerkersoftware?

### 1/5 — Soon

*2018-04-27*

Would like to see app use for testing 350. Don’t use a 330 only 350 so this app does not help me

No permite la conexión en plataformas iPhone año 2024 y aun no logra esta conexión

### 1/5 — Connessione molto instabile

*2023-06-29, version 1.5.1*

Il collegamento non è stabile, occorre riavviare app più volte ed essendo uno strumento di lavoro è penalizzante. Oggi ho dovuto salire su un generatore di vapore 5 volte per accoppiare da vicino lo strumento. Cambio analizzatore!!!

### 1/5 — 330xi won’t connect

*2022-09-22*

Was working on a page boiler today and really needed this app to work. It won’t connect to the analyzer. Both had Bluetooth on but it wouldn’t find any devices.

### 1/5 — ÇALIŞMIYOOOOOR

*2022-04-18, version 1.5.1*

İos için uygulamayı güncelleyin artık

### 1/5 — Won’t wok

*2022-03-09*

I cannot get app to see 330 analyzer. Useless.

**Developer response:** Please make sure that yo have the BT low energy installed in your device. Please go to device information. Next to BT should stand "LE" if this is not written, then you don´t have LE module installed. A upgrade of that BT module is not possible. Your testo team!

### 5/5 — Super Arbeitserleichterung

*2020-12-30*

Die Messöffnung vom Abgas befindet sich in >10m Höhe? Kein Problem! Kein ständiges hoch und runter auf der Leiter/ mit dem Hubwagen; sondern angenehm am Brenner die Messergebnisse ablesen und ggf. nachstellen. Klasse! 

Danke dafür!

**Developer response:** Vielen Dank für die 5-Sterne-Bewertung. Das freut uns sehr ;-)

### 5/5 — Works well

*2020-02-15*

Had my 330-2LL fitted with Bluetooth mainly as I wanted a Bluetooth printer 
It is a useful upgrade for today’s tec.

### 5/5 — Won’t work

*2017-11-01*

Can’t connect to App

### 4/5 — Hat schon was geiles

*2018-10-12*

Hab da gerade ein wenig mit rum gespielt da ich jetzt das neue 330 2 LL habe. Blöd das man Kundendaten nicht direkt eingeben kann aber die Mail Funktion find ich richtig top. Wird hoffentlich weiter entwickelt 👍 kann man auch über die App starten und stoppen, teilweise mal gut wenn man vor dem Kessel sitzt und einstellt muss man nicht ständig aufstehen.

### 4/5 — Немного нахватает

*2016-11-11, version 1.3.1*

Приложение хорошее, работает, при настройке котлов не надо бегать и смотреть показания, однако на андроиде функций больше, разработчикам есть над чем поработать!

### 3/5 — Compatibility with T300

*2022-06-04, version 1.5.1*

Are there plans to make this app compatible with the T300. It would make work so much easier.

### 3/5 — Kind of works.. requires several restarts to connect... once connected works.

*2017-06-12, version 1.3.1*

I upgraded my Testo 330-2G with Bluetooth module and download app. Tried to connect on IPhone didn't work... iPad connected after several app restarts. Once connected information was there the start/stop function worked. APP fairly basic but does what I need.... hopefully an update is due.. doesn't work with iPhone 7:-(.... hopefully update due?

### 3/5 — Da approfondire

*2016-02-14, version 1.1*

App salva analisi di combustione senza possibilità di attribuirne il nome.Non si può  salvare dove risiede l'app

### 3/5 — Ausbaufähig! Aber ok

*2016-01-08*

Der Zugriff auf das Messgerät ist noch etwas eingeschränkt ! Aber auf einem guten Weg. (jedoch noch viel Arbeit für die Programmierer)
