1. 4/5This app is almost perfect

   This is a great interface for the FLIR ONE. There are a couple of things that would make it even better. Most importantly: Please include an option to change where the take photo button is!!!! This button is on the bottom of the phone for the normal camera app because the camera is on the top of the phone. However, the FLIR ONE is one the BOTTOM of the phone, so the take photo button should be at the top. With the button so close to the camera, it’s not possible to hold comfortably, and I have to spend more time carefully positioning my hands. Even then, I sometimes miss when my hand is in frame of the visual camera (which is above the infrared camera). Please allow us to move the button. Some non-important things are the repeated request access to bluetooth popups when I’m not using a camera that requires bluetooth are annoying. I’ve also encountered issues when leaving the app while the camera is connected then going back into the app—sometimes I have to disconnect and reconnect the camera to get it to work. I’m in love with the fact that there is an app that makes sharing pictures with others easy.

2. 2/5Missing 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.

3. 1/5Poor 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.

4. 3/5Great device but MSX mode is meh

   This is a very cool device. After a short charge it connected to my phone/app without any issues and I was immediately able to see warm and cold spots in my walls and ceilings. I’m very impressed. My only criticism so far is the MSX mode. They’ve gone to the trouble of adding a visible light camera so they can overlay the images, but the system just uses the visible light info to generate artificial lines that are superimposed on the IR image. In many cases this detracts from the image rather than enhancing it. I would like to have the option to blend the visible and IR images with adjustable opacity, with the option to turn off the artificial lines. That would produce better images in my opinion. I’ve actually used my phone camera to take a photo and blended it with the IR-only image using a theirs party app and I like the results.

5. 1/5Latest version breaks device

   The new version of the app is incompatible with my gen1 device. FLIR’s solution? Turn off auto updates and don’t update the app. Except those who have auto updates enabled will have already received the newer version. Brilliant! They could have released a separate app for their newer devices or a legacy app for their older ones. But no, if I managed to find out about this problem before receiving the update then they think it’s best that I forever manually update all my apps. And not with taking “Update all”. No, I get to tap “Update” next to each of the dozens of app updates I get — and that I should do this on every one of my devices. To add insult to injury, when people complain about this in the reviews, they just respond with a generic “please call tech-support” message — as if that would get us a solution other than the idiotic one they’re forcing on us. FLIR has revealed itself to be both lazy and incompetent.
