User Reviews

Reviews are mixed to negative. Users like the app’s ease of use and find it usable when devices stay connected, but widespread issues dominate: unreliable Bluetooth connectivity, frequent crashes and logouts, updates breaking features (with requests to rollback), incorrect or missing readings and diagrams, and login/sign-in hurdles. Fieldwork is hindered by offline/login frictions and multi-device usage problems. Overall sentiment is frustration with reliability, despite occasional positive performance when connections hold.

Pros

Easy to use / intuitive UI
Works when connected to compatible devices
Useful for HVAC/refrigeration measurement workflows
Positive basic usability feedback (e.g., 'It works', 'good')

Cons

Frequent Bluetooth connectivity problems and inability to connect to devices
App crashes, instability, and constant logouts
Update-related issues: forced updates and breakage after updates; rollback requested
Data display problems: readings not shown or incorrect, diagrams misrendered, and settings not saved
Login/sign-in issues hindering calibration and use

The app makes me log in everyday. I cleared the cache, uninstalled and reinstalled the app same problem. The probe mapping does not save. I have to select the probes by the last 3 digits of the serial number which are very small to read. Can we name the probes when we set them up the first time so we know which probe is which every time? I feel the Testo app should be just as good as the hardware. There is another app that nailed these features but lacks the look and feel of the Testo app.
