Fixed an issue with the device list

User reviews

Context please!

Two big complaints. If the app fails to reach the detector, instead of retrying and automatically connecting when the detector is available again, it asks ME to reconnect it.
Historical data is shown without the obvious context you want to see… the Radon level was high, when was it high??? The app knows the date and time of day but does not correlate the data in those normative terms. Crazy.

Terrible app

I cannot connect to cellular

Does not provide time stamps

It seems to be a good radon detector, but when you go to review the measurements, there is no time stamp.

So while you can track radon exposure in a linear fashion, you can’t compare one date clearly against another.

App and unit aren’t connected long distance

The unit seemed great. Was giving readings on the app just fine. Until I left town. Now the app tells me the unit has disconnected and if previous reviews are correct, that means that the unit has turned off and I’ve lost all of the data previously connected. This seems like a huge issue and the company should address this immediately. Until then, I will be returning the unit.

Great App that just works

FYI: RadonEye app will only read from the device when within range of Bluetooth. Apple HomeKit integration would be perfect so I could automate a Raydon exhaust fan to operate within a set range or once in alarm range.
