Absolutely will not be recommending Flir to anyone ..ever ### 1/5 — Waste of space *2026-01-21, version 6.4.6* Over the 6 years I used this, what was once a wonderful and 5 star app, it has always lacked some basic functionality like reading the numbers or transitioning from thermal to regular camera but since the latest update the camera doesn’t even work now. It shows connected in the settings, shows the firmware and serial number but no longer displays the infrared image. I wouldn’t bother with FLIR anymore if you’re looking for thermal imaging. Much better to go with PULSAR or SEEK or any European brand with more modern sensors and without the 9Hz limit that plagues all the FLIR products. FLIR’s anti-Ukraine stance is another reason not to buy. ### 1/5 — Keine Verbindung möglich *2026-01-16* iPhone 15 Pro Max, Flir One, keine Chance das ganze zu verbinden. USB C steckt, App wartet auf Verbindung, Kamera LED blinkt grün und trotzdem verbindet sie sich nicht. Auf Android Geräten funktioniert es. Leider das Geld nicht wert. **Developer response:** Wenn die Kamera auf einem Android-Gerät funktioniert, ist sie nicht mit iOS-Geräten kompatibel.

So there’s no reason it would be broken. With the latest version, the connection step animation runs, and the green light blinks on the flir. But the app doesn’t proceed forward to displaying an image. I’m using Iphone XS with latest ios18 and lightning port. Jan 2026 I trouble shooted the settings app, toggling them made no difference. Also reinstalled the app. It worked before. App version is all that’s changed. Kind of a huge expensive bummer. ### 1/5 — Flir One Edge problem *2025-12-29, version 6.4.6* The camera was working correctly but then I updated Apple iOS from version 26.5 to version 28.1 and now the camera refuses to connect. Tried repeatedly but no luck but then attempted to go to the link to provide more information but the link is not working ### 1/5 — Garbage product *2025-12-24, version 6.4.6* Doesn’t work. $300+ for a hardware accessory that won’t even connect. Absolutely disgraceful. DO NOT BUY unless you’re happy totally wasting your money ### 1/5 — Flir *2025-12-19, version 6.4.6* Battery life is awful and can’t be serviced by the user. ### 3/5 — New app not as great *2025-12-15, version 6.4.6* I love my camera but the recent app updates have been clunky. I have a lightening port version of the camera and it used to work great. Now it has trouble connecting and disconnects for no reason. ### 2/5 — Not as anticipated *2025-12-13, version 6.4.6* Poor connect-ability making setup take tens of minutes not seconds. User interface not great either. For the cost of the kit, which seems great, the app seriously lets the side down ### 1/5 — ?? *2025-11-21, version 6.4.6* Again another app downloaded to my acct yet I have no prior knowledge knor consent of signinh up for this app, yet a bad actor whom hijacked my life has downloaded it to my acct and continues to exploit me on the daily!!! ### 2/5 — Flir One Edge problem *2025-11-18, version 6.4.6* The camera was working correctly but then I updated Apple iOS from version 26.5 to version 28.1 and now the camera refuses to connect. Tried repeatedly but no luck ### 1/5 — Image alignment *2025-11-10, version 6.4.5* Cannot align visible image with thermal image. Slider only does minor shifts. ### 1/5 — Scam - won’t connect *2025-11-09, version 6.4.4* I have a flir one edge, and it only connects about one in every 20 attempts. It’s so unbelievably frustrating that I want to throw the damn thing out the window. I spoke to their support and they told me to put the phone in airplane mode to connect. Which does nothing to help. I feel like this device is a complete scam, how hard is it to get a device to pair with a phone in 2025 for gods sake. ## Most critical reviews (10 lowest-rated) ### 1/5 — Doesn’t work on iPhone *2026-08-11, version 6.4.12* Tried to connect Flir to my phone but failing, no proper documentation that can help me figuring out. It couldn’t detect the camera. Works fine with another phone (Pixel). ### 1/5 — App does not work on iphone 17 pro max. *2026-07-26, version 6.4.12* I plugged in my flir one after fully charging it, held the power button and then waited for it to start flashing green, and it just sat on the stupid screen telling me how to connect. Tried fully uninstalling and reinstalling the app and the same problem. The camera worked fine on my android, so I can only assume it's ios being garbage. Putting 1 star for now, if an update is put out fixing it I'll give a 5 star which is what it would be if it connected. ### 1/5 — Funktioniert nicht *2026-07-06* iPhone 15pro, also usb c. Sollte eigentlich funktionieren. Ich stecke das Gerät an, App ist geöffnet und befolge die Anleitung, so wie sie angezeigt wird auf dem Handy. Die LED leuchtet grün, aber in der app springt es nicht auf die thermalsicht um und bleibt die ganze Zeit bei der Anleitung hängen. Bei einem Kollegen mit Android funktionierts problemlos (gleiches Gerät). **Developer response:** Hallo, vielen Dank für Ihr Feedback.

Well beyond what i am comfortable agreeing to. ### 1/5 — Bad customer service *2026-02-16, version 6.4.6* The worst customer service ever, I spent over $400 on the camera, sent many emailed to customer service and received no answer, tried to call and that didn’t work. Don’t invest with this crabby company ### 1/5 — Pairing issues *2026-02-08, version 6.4.6* Pairing with the Flir Edge Pro camera can sometimes be tricky, taking longer than expected, not recognizing the device, or buffering frequently. That can be pretty frustrating. I think it would be really helpful if it could automatically connect to your phone via Bluetooth and show up instantly in the app without any manual steps. ## Most praised reviews (10 highest-rated) ### 5/5 — Great tool to see heat loss *2026-01-12, version 6.4.6* FLIR helped us target areas of heat loss and address them . Looking forward to lower fuel costs ### 5/5 — FLIR is love *2025-12-16, version 6.4.6* I would like to give FLIR the highest possible rating and they have great customer service. Thank you so much 😊 ### 5/5 — Great for finding animals *2025-11-17, version 6.4.6* At night I look for rats and raccoons I’ve found a family of raccoons and a lot of rats running around in the forest with this, it is also good for finding leaks. ### 5/5 — Founder *2025-11-11, version 6.4.5* Outstanding ### 5/5 — Great tool for the kit *2025-11-07, version 6.4.4* valued piece of tech. I rescue animals. many are new born, kittens especially, they’re dropped off at night by people with no good sense. I use the FLIRONE to find them in the dark. They’ve run and hid in the ground cover and cry. Their crying gets you close enough to you the FLIR then they glow bright in the pitch dark. FLIR has saved a lot of these cute little critters from a bad way. The price is perfectly fair and a piece of FLIR tech should be in everyone’s toolkit. ### 5/5 — Finding leaks *2025-11-05, version 6.4.4* It’s been super helpful finding leaks throughout different buildings of property that I manage! ### 5/5 — Good quality for the price. *2025-10-28, version 6.4.4* Not great resolution but, for an amateur, an excellent tool for the price. ### 5/5 — The best device ever *2025-10-24, version 6.4.3* Love it ### 5/5 — Paid for itself in one job! *2025-10-10, version 6.4.3* Excellent affordable option for home inspection. Found two showers leaking and disconnected HVAC before removing walls! ### 5/5 — Swiping *2025-09-10, version 6.4.3* Please bring back the ability to swipe between the thermal and regular images. Previously, if you slowly dragged your finger across the live image, you could see the transition. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
