Either gives an error when scanning or app crashes and closes. Shocking poor for something that is relating to health and safety. ### 1/5 — Doesn’t work 🙄 *2024-11-06, version 1.0.3* Useless ### 1/5 — App does not work *2024-10-23, version 1.0.3* Just bought a Firehawk carbon monoxide alarm which came with a leaflet for this app. Followed instructions but the app closes itself down. Tried to email them and the email does not get delivered. Deleting app as clearly it doesn’t work with iPhone 14 Pro Max. ### 1/5 — Worst app I’ve ever seen *2024-10-17, version 1.0.3* I tried the app on two iPhones and an iPad, it failed to work on any of them, producing an error message every time and on two of the devices the app crashed. The reviews don’t appear to reveal a single user who has got it to work. The developers should be ashamed of themselves if this is the best they can do. The manufacturer would do everybody a favour if they simply stopped telling customers that there is an app. Fortunately the alarm doesn’t need the app in order to work, otherwise I would have sent it back. ### 1/5 — Useless waste of data space *2024-09-05, version 1.0.3* This app does nothing, the scanning process doesn’t work and just constantly shuts down the app, don’t bother. ### 1/5 — Crashes on registration attempt *2024-08-08, version 1.0.3* As most people state the app fails to register a device. It either scans and errors or when you get the camera close enough to the camera and see the red lines the app just crashes. ### 1/5 — Doesn’t work *2024-06-29, version 1.0.3* Absolutely useless, an app that is for health and safety purposes should function correctly, when you attempt to scan the device the app consistently fails to read any information, and constantly crashes. ### 1/5 — No longer supported *2024-03-19, version 1.0.3* Changes to iOS has made this app unusable and the developer is no longer supporting. Contacting the manufacturer proved fruitless ### 1/5 — Waste of time *2024-02-25, version 1.0.3* App needs removed from store as it’s useless. ### 1/5 — Rubbish *2024-02-18, version 1.0.3* App crashes every time ### 1/5 — Fire hawk app *2024-01-21, version 1.0.3* Does work absolutely terrible. ### 1/5 — Useless *2023-11-26, version 1.0.3* Tried multiple times - doesn’t work at all as others say it errors or crashes the app. Useless. ### 1/5 — Doesn’t Work Don’t Waste Your Time *2023-10-25, version 1.0.3* Tried several times to get this app to work. But every time I try to scan the alarm’s red light with the scanner, I get an error message telling me to try again. Waste of my time. ### 1/5 — Fail *2023-10-17, version 1.0.3* I can also confirm it doesn’t work. What is the point? ### 1/5 — Does not work *2023-10-15, version 1.0.3* Tried several times to scan moving the camera closer and further away. Either comes up as error or just crashes. Deleted the app as it is of no use. ### 1/5 — Waste of Time *2023-03-21, version 1.0.3* App crashes at the scan section. Gave up after 10th attempt. Sent off to supple and await response. ### 1/5 — Waste of time *2023-02-23, version 1.0.3* Rubbish app. Keeps crashing after scanning the device. iphone has software 16.1 installed which is more than is asked. Tried 10 times with two different CO monitors and has crashed every time ## Most critical reviews (10 lowest-rated) ### 1/5 — Useless *2026-03-22, version 1.0.4* Scanner doesn’t work and even if it did the app is limited. Totally useless. I’d give it no stars if I could. ### 1/5 — Doesn’t work *2025-12-05, version 1.0.4* Got a monitor from a local charity as I didn’t have one. When scanning into the app, the app just crashes. Tried a few times so can’t use the app. They need to improve this as it’s an important piece of kit that should alert you if needed. Don’t offer an app if it is not working!! ### 1/5 — Useless *2025-10-20, version 1.0.4* Doesn’t scan, doesn’t do anything. Pointless. Should’ve bought the base model and saved an extra couple of quid! ### 1/5 — Junk - not worth 1 star.. *2025-07-06, version 1.0.4* App crashes every time you try and capture a picture of the display within the circle as stipulated. Therefore it’s utter JUNK.. ### 1/5 — Newly installed CO Alarm *2025-05-07, version 1.0.3* Installed app and as per all other users just comes up with one screen asking to scan the alarm, then fails. Waste of time. Clearly after 3 years still not resolved the issues. Downloaded to an iPhone 15 pro. ### 1/5 — Won’t connect to CO alarm *2025-04-12, version 1.0.3* Repeatedly errors. Gave up. ### 1/5 — Useless *2025-03-21, version 1.0.3* Fire brigade & gas safety board gave us 2 new FireHawk CO detectors after a carbon monoxide scare. Was told we could use this app to check data on CO alarm but the app is absolutely pointless. Alarm is beeping but unable to scan the alarm to check what’s wrong as the app crashes every time. Don’t waste your time. ### 1/5 — Crashes or gives error message every time *2025-02-19, version 1.0.3* Hopeless app - let's hope the actual detector works! ### 1/5 — Firehawk Data Scan *2025-02-07, version 1.0.3* What a load of rubbish doesn’t even read the alarm when red light flashing, was going to give zero stars for wasting my time but it wouldn’t let me ### 1/5 — App doesn’t work *2025-01-15, version 1.0.3* Probably a development project for internal use only. So buggy it doesn’t even work. Shame, it was a cool idea! ## Most praised reviews (2 highest-rated) ### 5/5 — FireHawk Data Scan *2025-12-19, version 1.0.4* Never had a problem with the app not working from iPhone 7 right through to iPhone 26, just lay the camera lens on top of the led, if the bar doesn’t fill right up just press scan again works every time. ### 3/5 — Works as intended but… *2026-03-15, version 1.0.4* As MrDead63 wrote, you need to put the phone camera as close to the diode as possible, and fill the entire screen. The green circle is just misleading. Forget about it. A bit fiddly with my sensor being attached near the ceiling, but doable. Would be much better if the instructions were clearer. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
