### 1/5 — Useless app!!!

*2022-08-29, version 6.19.0*

Works good. But interface is not beautiful!

### 1/5 — Worthless

*2021-11-16, version 6.19.0*

I bought two sets of Smart probes and an IPad thinking I could use them on twin circuits, one set with the phone and the other set with an IPad. 
It refuses to run both sets of probes at the same time, making them totally useless for Commercial and Industrial units.

### 1/5 — Useless, won’t work with my Testo tools

*2021-06-11, version 6.19.0*

I own 8 tools and Payed fair amount for them. 
Only way I can use them is with MeasureQuick!
  Pressure gauges are accurate in MQ on test bottle and able to Zero. And also can calibrate my temperature sensors. 
 Can’t get my LP gage to zero or read psi in Testo. 
  Very disappointed ,sensors expensive junk if you can’t read them!

**Developer response:** Please switch to our new Smart App in the Appstore. Performance issues should be solved there in any case. You will also be impressed by the new design and user interface. Your testo team!

### 3/5 — Ability to save favorite Refrigerant needed

*2021-05-12, version 6.19.0*

The app works pretty well. I’ve used it for years and have learned how to deal with it. My 2 main complaints is when you lose signal with your probs they don’t auto reconnect, you have to close out the app and then they will reconnect. And the lack of a favorite list or the ability to reorganize refrigerants like you can in the testo manifold app. If that small change could be made I could give it a higher rating. But with the amount of time I spend each day scrolling through the refrigerants list makes me want to try the fieldpiece probes.

### 2/5 — There are better apps for connecting these probs to

*2021-04-29, version 6.19.0*

This app is 5 years behind the competition. Its like they lost interest in the app after manufacturing the wireless probs. It needs a major update.

**Developer response:** Please switch to our new Smart App in the Appstore. Performance issues should be solved there in any case. You will also be impressed by the new design and user interface. Your testo team!

### 3/5 — App clarity

*2021-03-16, version 6.19.0*

App is great, could be a little more fluid and also when attaching pictures or saved pictures from Testo devices to add on the work order, pictures are blurry and cannot read and also make out what the picture is of. 
Please fix the picture portion and it will be a great app !

### 1/5 — Why separate apps?

*2020-12-14, version 6.19.0*

Why can't I use my 550 with a 115i? This is beyond silly.

### 3/5 — Apple Watch?

*2020-11-19, version 6.19.0*

Can you integrate with Apple Watch , would like to monitor one reading on watch?

### 3/5 — Spelled “mold” wrongly says “mould” risk

*2020-03-28, version 6.19.0*

I like the app for the most part. Could be more user friendly. I would like to see a few more training videos and some updates.

### 1/5 — App needs help!!!!

*2020-03-14, version 6.19.0*

My sc reading won’t show 🤔
