Rubbish app and design

I have been using the probes and app for over a month now, and to say I’m disappointed is an understatement! Testo are supposed to be the leading manufacturer in this type of gear.
Ok... the app.....
-Drops Bluetooth all the time, you need to keep reconnecting probes, only to find they won’t connect so you have to uninstall app and reinstall, set everything up again and start over. If you saved details on there it’s best to create a new contact as you will need to keep reloading and reentering the info.
-only allows 1 entry at a time, write report, send, start over, nightmare of like me you have multiple units per day to do. There’s no options to do multiple reports and send as 1 pdf.
-unable to edit the name of probes, it’s set as the testo probe name ie 549i or 115i, no option to properly name these Low/high which makes reading reports tough. (Get a grip even Trane have a better system)
-unable to edit the your own comments in the comments section, nightmare! Make a mistake or want to add a new value... guess what, start over again.

The idea is here with these and I would of hoped the app would of been more like the testo easykool software which was brilliant, sadly not, and testo customer support don’t give a crap about the app just the sales of hardware, 45mins waiting to be cut off, and when I finally got through told to just restart app again!

If I could give 0 star’s then I would!

Testo fridge app and senders

This is the most incredible app and Bluetooth refrigeration monitoring system ..stunning
The app shows so much information and the quality of the Bluetooth senders is faultless how do they do it for the price.
Bluetooth connects every time best money I have spent 😀

WARNING - it doesn't like ISO10

These are brilliant refrigeration tools and if you utube senoj60 you can see a genuine review of them !
But they have failed with keeping pace currently ( September 2016 ) with ISO10 the encodes have messed with program displays causing a serious issue which renders the tools useless until rectified works fine on lower versions !
