Small changes would make a big difference

The app is easy to get up and running. However, there should be a setting to disable the loud beep each time a Bluetooth connection is made. That quickly gets very annoying.

The graphing of data really misses having a time stamp on the x-axis. It makes trying to understand daily patterns painful. Even the exported data doesn’t enable time tracking easily. So the whole feature set of having trend data is really crippled by this omission.

Otherwise, very pleased with the monitor so far.

Save your money. Use another brand

I was a radiochemist for over 8 years and worked five of those years at a nuclear reactor. That doesn’t make me an expert on radon by any stretch but I suspect my experience gives me a perspective that your typical home radon testing consumer doesn’t share. What’s remarkable to me, however, is that despite my background, I feel exactly as other do: This app needs work. The fact I can’t do something as simple as rename a device to, for example, “Utility Room” speaks volumes. So, too, does the chief complaint expressed by many reviewers here: The app will not allow one to plot radon readings in a way that’s easily understood by your run-of-the-mill consumer. I should be able to select a date and time and the graph should return those readings. Why is something so simple out of reach? I suspect it’s because this company neither has the staff nor the expertise to address the app’s—and to a lesser degree, the RadonEye unit’s—glaring shortcomings. Nothing says “I don’t care!” more than a company that hasn’t updated their app in over 4 years and that’s why this gadget is going back.

Poor connectivity

This app is constantly disconnecting from my bluetooth on iphone. The device then shuts itself off because it can't function without a bluetooth link to a smartphone. This is very annoying as you essentially can't use your phone for anything else unless you're sitting right beside the RadonEye.
Oddly it doesn't appear in the phones normal bluetooth menu where all other devices would appear. So it seems the developers chose to use some different method than literally everyone else to pair up and I suspect thats why it doesn't work.
After a lot of cajoling and babysitting I can get the device to do it's job maybe 60% of the time. The rest of the time it fails. It disconnects from bluetooth then turns itself off.
Maybe the developers could have thought to try out their product to see if it works??
Yes, yes, you should try it out before selling it.
