Flir one is an incredible tool

This update is a great improvement over the previous major version. The auto ranging now gives a much more contrasty image without having to move it over to FLIR tools, and I don’t know what the secret sauce is behind the image stacking or whatever FLIR is doing to improve image sharpness but it too seems better. Now, if FLIR would offer some sort of battery replacement program for my FLIR One Pro, I could enjoy this for more than a couple minutes at a time.

Missing Features for FLIR One Gen 3 ?

I purchased the FLIR One Gen 3 to use with this app after reviewing a digital manual of the device which included very important features for IR Scale and Lock Span. Neither of these features seem to be available for this device when using the app, even though the manual clearly mentions them for the non-pro device. Am I missing something? The device seems great but requires the app to use it and from what I can see, this app is extremely limited in capability, which really downgrades the user experience. Without these critical features, I wouldn’t recommend the product and might suggest look at other brands.
Added detail: I reached out to FLIR technical support shortly after the original comment here (4 months ago) and did receive feedback - but was not helpful. I was basically blown off and told IR Scale and Lock Span were no longer available on this device. It would be one thing if the device hardware limited these features, but that is not the case here. This is obviously a deliberate attempt to limit user experience on lower cost units in the hopes to drive more sales on higher priced devices. If you are going to do something like this, do it from the start and don’t remove functionality after it was previously available. That’s pretty low. And please don’t provide a canned response that “you’ll look into it and review” when there is clearly no intention do so.

Poor Photo Permissions

Dear developer, Please refer to the PhotoKit documentation. As a user, if I grant access to “select photos” your application should still be able to take pictures and write photos to the photos library. You shouldn’t need read access to every photo I’ve ever taken in order to function properly.

UPDATE: DO NOT BUY FLIR PRODUCTS. As you’ll see the “developer” commented that I can reach out to support and they appreciated my feedback. That’s just generic customer service jargon and it means nothing. The truth is it’s just another company with outsourced support and they don’t care about the end user. I created a ticket with their support team over a month ago on July 21st, 2023 and provided all the details on how to implement the change to fix the bug. As a developer myself, I know this is a simple bug fix. No one has followed up. I also followed up again on July 29th, 2023 and still have not received a response from their support team. If you spend over $500 dollars on a product it should work out of the box. The lack of correspondence shows this company sells products that they don’t intend to support. I have since shipped back the product and will never buy from them again.
