FLIR ONE Reviews

    So far so good

    I have the third generation Flir One, just the regular one, not the Pro. I connected it to both my iPhone and my iPad with no problem. I am on OS12 for both devices. I updated the firmware of the FLir One first thing. I do not allow location services and I have never created an account or (of course) logged in. App doesn’t seem to mind and works as advertised. Angle of view is small and resolution is not great, though I would say the images taken with the iPad are perhaps better than those taken with the iPhone so maybe it’s not the fault of the device. But in either case the images are perfectly readable and very informative. Looks to be a useful tool. I will update this review if warranted. I bought this device for a specific project and I am just learning how to use it.

    Unreadable numerics

    First, the hardware is really quite good and the app as a whole is well-done. However, the font used to show a measurement spot is almost unreadable against lighter colors and this makes it very disappointing for trying to measure things. The font size is large enough but it needs more of a shadow outline or thicker stroke or something and the transparency should be removed. Another issue is there are very few options for emissivity and no way to set it correctly for human skin as you can with other thermal cameras. It would also be nice to be able to set a temperature threshold instead of only having the "hottest" LUT which varies, 36.3 C with skin emissivity set would be incredibly super relevant right now for obvious reasons.

    Expecting better from Flir...

    I downloaded this software to use with a Flir One Pro LT. The instructions that came with the camera contained only one real instruction: download Flir One app. The Flir one app provides no detailed instructions on first use of the camera nor a description of the charging time before first use. The app itself appears to have a clean design, but the inclusion of a watermark on every image effectively reduces the resolution of this device. My Canon, DJI, and Sony camera gear don’t include this and neither does Flir’s more direct competitors. I’ve used Flir products previously and the hardware has been pretty solid, but the accompanying software is consistently disappointing. To the point that I may return this camera and replace it with a lower cost competitor, thus eliminating the need for this app.

    Flir one is an incredible tool

    Only a couple years ago I only had access to thermal imaging when I could reserve the multi $$$ unit at work. Now I have it in my pocket. Of course there is a quality difference between this and a T-400, but being able to carry such a powerful troubleshooting tool in my pocket still blows my mind. That being said, the app still has some bugs that need squashed. The image parallax adjustment only works in one direction, but the high range temperature readings are finally more in line with reality.

    Had SW/HW issues, but support ultimately solved them

    I was using this app with a Flir One gen 2 on a 7 Plus. No matter whether both camera and phone were fully charged, as soon as I connected or powered on the camera, I heard a couple of shutter-like sounds, and then the app would exit. Seemed like a software crash to me. After initially trying to make me discharge the Flir One battery, which after 10 days was still half full, support replaced the unit, and I have not yet experienced the issue again. The app and hardware feel good, being able to see in a new dimension is a revealing experience. Found it useful for insulation issues, water leaks, heating, even to have a closer look at electrical and electronic components. Where there is heat, there is often waste, or a malfunction. 5 stars because results are what count, and support left that good final impression.

    Works pretty well, one complaint though

    So I have the FLIR One Pro, and this app actually works pretty well with it. I really don't have any issues with actually using the camera. My problem comes with the file naming. Every image seems to receive the same exact file name on the same day pictures are taken. Please look into this issue, when I upload images to OneDrive, they have to be individually renamed by the app, so I have to click through each picture to retry upload.

    FIXED: Communication error

    Update: Per developer recommendation, update to iOS 11.2.5 resolved communication error. MSX alignment and temperature readings seem to be good. Thank you! Horizontal bands persist until manual calibration. Original: Gen 1 on 6S. I’ve had the gen 1 since release. Used to be a great tool but app/updates have handicapped the flir one. Latest app version 3.1.11 still has not fixed “communication error”. Temp readings inaccurate. MSX alignment off. Horizontal bands in image until manual calibration. It has been 1 month since last app update. Please fix!

    iOS 10.3 Beta Test

    Update: I just upgraded to iOS 10.3 Beta, and was able to update the FLIR One firmware. When I first tried the update it failed because the FLIR battery was too low, so I tried plugging it in and ran the update while charging. The camera successfully updated I noticed the charge indicator go from about 55% to 99% in a short period of time. I’m increasing my rating from 1 to 4 stars for now until I do further testing. I will update soon.

    Latest software fixed issues

    Update: most of the issues appear to have been resolved by an update, so I’m revising my review to reflect that. It works again for me. —————— The latest software ruined this now-overpriced device. I don’t see why it had to be “dumbed down”, it was much better before. Battery life has gotten worse, temperature readings no longer work, and the screen frequently becomes laggy or unresponsive.

    Slow software fix

    I’ve had gen2 flir one for a few years now and the app while not spectacular it gets the jobs done. I’ve used it helping a few things while traveling. Yes I keep it in my backpack when traveling because it’s compact and it’s a very useful tool everywhere. Then IOS 12 came last sept and flir one app crashes whenever camera is attached. Filed support case and its said to be escalated for fix. I know it’s iOS 12 that broke the app, but the pace of software fix is a concern for future purchases.

    Good except watermark

    The abilities of the tiny device and this app seem to nearly match much larger and more expensive thermal cameras. I’m impressed with the ease of use and variety of settings available. As some other reviewers have mentioned, the app watermarks all of your images with the FLIR branding, and there is no setting to turn this off. This seems presumptuous and a little annoying.

    MSX needs improvement

    This should be an easy issue to fix so I’m not sure why the developers have not done it yet. The MSX is often misaligned in the horizontal direction, But currently it can only be adjusted in the vertical. This makes alignment difficult. And sometimes if you are taking a image that has both near and far objects in the view, the MSX You’re only align with one of them, If the MSX could be stretched, this problem could be easily solved.

    It works, but needs some TLC.

    The interface is a bit klunky and not very intuitive. Functions like selecting multiple photos are organized differently than Most other apps and it makes for a bit of a learning curve. Some features are not functioning. For example, when sending an image, there is a option to send using WhatsApp. When you try and do that, no image is sent.

    Can't take video

    Just got a Gen 3 one and am using it with an iPhone XS. There seem to be many things that are in the manual that I'm not seeing. Temp range for example. I've not been asked to create an account to register, and everything seems to be going fine when I record a video, but I can't save them and when I try to view them they only play for a split second. There is also no option to check the firmware. Phone is running 13..3.1

    Doesn’t work

    Update! latest release no longer stuck at -50C except reading reads approx 10F than it should be. Tried it with iHone 5 with IOS 10 and it reads fine. How can we trust the reading from this device? Just bought my Flir One Pro for $400. I was excited to use it as I will have a lot of use for it but when I plug it in, it doesn't work. Reading is stuck at -50C. Just paid for something that doesn't work. I will give another week before return policy expires and if no fix, this unit is going back.
