FLIR ONE Customer Insights

1. Absolute piece of junkA buggy and slow experience with the FLIR ONE Pro... The device takes a long time to start up, connection with the phone seemed unreliable, and I experienced regular crashes of the app.

2. I do wish it was more customizable,I wish even More that I was able to measure two different temperatures at the same time i.e. high & low and/or a touch to get temperature function in the live view.

3. There's a third party app I use for the Flir One that has all sorts of nice features such as changing the color scheme and locking the temperature scale so it isn't constantly adjusting.Overall adequate.

4. Even with them not all in frame at the same time.Each update has made the connection slower and slower to the point it wont connect anymore.

5. Rather being able to lock the temperature range eg from 0C to 50C, the false colors are always adjusted relative to the min/max in the current image capture.

6. Maybe the bad reviewers are using a cheaper phone? Or have a bad flir device? Idk.

7. I wish I had checked them before I made my purchase.When will Android 14 update be released for the app? It's a hassle to have to use two phones when switching to the newest pixel.

8. This makes finding building issues very complicated.No issues with connectivity like other reviews are saying, but I wish the app had more features.

9. My pixel 6 is running the app maybe for 60 seconds (if it connects at all) before loosing the connection to the flir sensor.

10. Typically by the time you take the camera to the area you are trying to look at it has disconnected and possibly ran out of battery from the time spent fighting with it.

11. Installed the app on an older Motorola phone and it works fine.
