First it’s not at all clear that it is secure. It feels like the synchronization with the network leaves an unprotected entry point for hackers for each device. I feel like if it were secure, they’d make that clear. Second, the setup should allow you to set your parameters for all your leak detection devices at once-get all (in my case, 5) units in the app and named, then ask what parameters I want (humidity and temperature alarms), then apply them to all my units. Likewise, I shouldn’t have to add an address for each unit. It also appears that using a separate network connection seems to add a new home (if I try to use the existing address it says that address was already used) and it doesn’t ask if I want to use that existing address. Once you add a second address, there’s no way to delete it short of deleting the app (that I could find). Finally, if you set a parameter too low, or get a disconnected from the network notification, troubleshooting does nothing but bring you in circles. ### 1/5 — Rubbish app *2026-08-05, version 8.23.0* This app is terrible, and their “smart” devices are even worse. Constant network issues. Says the device is offline, then goes back online randomly. Changed my wifi network, and do you think it’s easy to pair the device to my new network? Of course not. I follow the instructions in the app, and it says “Pairing Error - No device found”. Don’t waste your money. I have no idea if the device is working or not, as it says it’s offline. ### 1/5 — Crashes when setting up *2026-07-25, version 8.23.0* This app is total garbage. It crashes all the time when trying to set up new devices. ### 3/5 — Device *2026-07-20, version 8.23.0* Need to be able to put on more than 1 persons device. Was away and my husband called and had rude customer services since change over. No water for one 2 hours. Live on horse farm need to fill water. Explained to repressive and was giving rude answers. “You have leak! “ my husband and daughter need capability to handle device as well. ### 5/5 — doesn’t work well and not user-friendly *2026-06-25, version 8.23.0* Sensors don’t do what the app says they are supposed to do i.e. pairing them does not work as it says it is supposed to work. If they go off-line, it is virtually impossible to re-pair them. App crashes all the time. ### 1/5 — Terrible user interface *2026-04-16, version 8.21.0* Cannot use the app since it does not rotate. I use my iPad with a Magic Keyboard and am always in Landscape mode - app is always sideways for me ### 5/5 — Peace of Mind *2026-04-12, version 8.20.1* I can leave my house knowing there won’t be any bad surprises where leaks are concerned. ### 2/5 — Great System. App Annoying *2026-04-03, version 8.20.1* I don’t get why I need to sign in every time I open the app. Trust me someone not trying to hack my water usage. ### 1/5 — Constant logging out *2026-04-01, version 8.20.1* Since the latest update this app won’t stay signed it which defeats the purpose of having an app to track leaks. Every time I get out of the app I have to resign in. It’s ridiculous. How am I meant to get a notification for a leak when it doesn’t even work? ### 2/5 — Consistently buggy interface, useful in general, but irritating *2026-03-15, version 8.19.3* Consistently buggy interface, where buttons don’t respond, cycling through alerts you can’t exit or dismiss, and wonky UI. Constantly asking you the same question over and over and over again like plumber contact details. Just feels like they aren’t doing much consumer polling on improvements. Overall, it’s still worth installing for the emergency controls it offers, but could be a lot better and hasn’t improved in years. ## Frequently asked questions about Phyn ### What does the Phyn app do?
