testo Refrigeration

It's good for basic function. However it stops reading every 2 minutes or so. You can't let your phone go to sleep, can't get a call or text, can't open another app or even turn your back on it and it stops reading. It would be nice if this could run in the background like every other app!

The app works for a couple things. It's not great it could be so much better but it does work. Its nice to be able to record and send the system data to your customer. You only need to be linked up for a minute. Also I really like it for doing my leak/pressure test. It shows you the pressure every two seconds. So I'll leave my phone on the condeser for ten minutes and you can see exactly what your pressures were. You can also record that data and send that to the customer. I hate how difficult it is to type all the customer info in. Overall the app works but it needs work.

I have the 550 they work great just wish the app could store jobs and save jobs to the phone if needed instead of emailing all the time

Great app. For the money BT COULD have a better range. J/S

Would be nice to be able to save reports to a file or find them

addictive

The app is missing basic functions such as storing job info to review later. If you walk away from the Manifold while entering job info the readings disappear as I discovered on my last job and being limited to 5 lines in the comments section is kind of rediculous. Fieldpiece, CPS and imperial all have these functions built into the apps this really needs to be addressed.

There is zero written support for this product. In order to use the product, that is, once it ever connects to the 550 in this case, one has to go through each menu and figure out what does what, it isn't all that obvious. What's more, the display device, in this case an Android, the device behaves differently whether the display is held vertical or horizontal, the functions are actually different. I have to admit though, calling the distributor who I purchased the product from gave excellent verbal support. By this time, I've figured most of the report writing up, but what I still can't figure out is to show a "trending graph" and to send it out via email. I seem to be capturing only a few seconds, I'm told there is a way to capture as much time as we want, but haven't figured that out, nor have I found a solution on the internet. I don't think it's a problem with translation from German to English, I think it's an unfinished product, why no manual?

Doesn't keep recording when in background. If you get a phone call the app doesn't do anything until you make it visible again... Simple issue to get wright folks...

All data is lost once the testo 550 is off. I would like to be able to review data on my phone via the app afterwards.

Never make it work on my phone I don't know why they app download pretty good but it never show any measures nothing I don't know if he is because over here in Texas or that's not available to hit in Texas or my phone doesn't support or I don't know but never work

well it "works". but it is very poorly implemented. makes me very unhappy that i paid extra for Bluetooth.

Why is the suction side 6 degrees off on everyones meter....

Will not connect via Bluetooth

Can't connect it Bluetooth doesn't work

Great app

Keeps trying to send pdf reports through messenger app which doesn't support pdf... need to be able to select what application to open the reports with. Typical android garbage this app is.

The only reason I got the Testo's was for the bluetooth , it only works if your next to the manifold. That is useless to me because the reason for the Bluetooth and even buying these was to be able to adjust the indoor TXV's or airflow issues without having to go back out and check gauges between each adjustment. Gauges do work if you don't need this feature, but for me I will be returning them.

Can't save trend like with the Smart probes.

To another smartphone connect in few seconds

For the reason I would bet everybody purchased this digital manifold this app is almost useless. I did say almost useless. screen shots are useful to some degree for saving data to the device. I would also Bet that Your people are much smarter than this app would imply. By the way I am happy with the 557. Just not happy with how it works with the App. If I am missing something maybe detailed instructions would help everybody that has written pretty much the same review.

I had planned on getting the imperial manifold but the lack of a display put me off so I bought the Testo. After being happy with the manifold I fired up the app and was extremely disappointed, guys have a look at how the imperial app displays, that's how it should be done. I hope you update it soon and move from 2006 to 2016. And maybe look at your data logging, this was a huge plus for a digital manifold and your application fails on this front too. Good hardware, not so good software.

Really like this manifold, very affordable, whish it would update over the air like most cell phones.... very unstable bluetooth connection at 20 ft, Galaxy S6. the app needs more options and better design, instead of bluetooth signal, why not wifi. How about target superheat or subcooling

App crashes when my phone goes to sleep or I get a call. All data is lost when this happens. Bluetooth range sucks, why not WiFi? Really like the manifold, just wish the app was as good. Two stars for half assed app.

The app works great until I have to leave the app or phone goes to sleep. If that happens and I go back to the app it has frozen and I have to close it. I then lose all the data it has logged (my favorite feature). If the app is fixed so that I can take a phone call from my dispatcher with out losing the app freezing and if I could save my log and I could change my log rate to say 1 minute, 5 stars it has the potential to be amazing!

I don't mind the limited range blu tooth. The app, however, is a huge let down. I like that I can send a pdf with data to the office, but it should be easier than it is. The app freezes. It seems to not send all the notes I write. I dont like the terms "undercooling" and "over heating" instead of sc and sh. Please tell me there's a better version of this app coming soon. Ive been all testo for a long time, but im starting to question if field piece is going to be a better choice.

Theory is good but bluetooth is hit and miss. I work on commercial equipment so don't care about range of Bluetooth but the reports was my sole reason for buying the testo 557. Export graph fail, no option to select data to be on report so blank spots on reports. Still need to make a photo of gauge to show vacuum holding cannot export trend and app crashes if you try to screenshot. Happy with unit but like others think it needs a sit-down and rethink or the option to get an app written for own needs.

Love the gauges but , I can see the screen farther than its functional Bluetooth range. Very poor/unreliable connection.

Bluetooth very unreliable.. it works enough to get me hooked, and let's me down... Often. I like the other features though. The gauges? ... Love them. Wish the app worked as well.

Buy the tool but app not very good. All reviews about Bluetooth connection and crashes are true. Tool pays for itself very quick though

When i connect to the device why does my phone say manual mode does not work in app??

I try to put my phone number in and the app goes crazy jumping back and forth.

Great!

Returned testo system and purchased Sporlan's Smart Service Tool. More money but a lot less hassle.

Need to upgrade app to be able to operate on android version 5.0 and higher thats one reason i bought the testo 550 w/Bluetooth

Needs more Bluetooth power, 65 ft unobstructed just is not enough. Every attic is an obstruction. Extra money for feature that is useless in residential application. Not happy with that. Otherwise great gauges.

Doesn't work with gauges in auto mode for app

Great device. The Bluetooth is a great disappointment.The Bluetooth does not work at all. Should have bought a Fieldpiece instead.

Good , I can view the data inside the car .
