About this app

- All in one: The testo Smart App guides you easily and quickly through measurements on refrigeration, air conditioning and heating systems, air flow, and many more applications.
- Fast: Graphically descriptive display of measured values, e.g. as a table, for quick interpretation of results.
- Efficient: Create digital measurement reports including. photos as PDF/ CSV files on site and send them via e-mail.

NEW in the testo Smart App:
• Multi-site measurement PRO measurement program: With this first-class measurement program, you can create professional documentation of your measured values at different measurement sites.
• Air balancing PRO measurement program: Accelerate your workflow and eliminate errors: The new measurement program 'Air balancing' brings you more efficiency and speed in the commissioning and adjustment of ventilation and air-conditioning systems (especially for balanced ventilation systems).

It is hard to rate, because the functions and amount of things you can do are amazing, and for that i give 10 stars.. however the user interface is not very user friendly, and very difficult to maneuver. If Testo makes the app easier to navigate, and find the different settings and options, this would be the best app for any bluetooth tool ever made.

Bought new 550s because the 2 year old 550 would constantly freeze without notice. Now the new update crashes on S22 Ultra. Failure notice says: "testo Smart crashed because this app has a bug". They are great when they work, and the data is useful for troubleshooting. But for this much money this low level of reliability is hard to justify.

This is a little late in posting seeings how testo "Smart" has been active for some time.When i was using the testo smart probe app(the original app)life was swell. All i had to do was open the app ,turn on the probes & presto changeo, lines were graphing , tables were numbering.I could add or remove probes without disrupting the flow and when I was ready,save or send it as I pleased. PLEASE GIVE ME BACK THE GOOD TESTO APP!!PLEASE!!!!
