## RadonEye Reviews in United States

### **--- "Great device with a useless app in terms of data tracking"
How in the world can you build an app that does not provide the date and time of a reading!? Otherwise, I really like the device. The frequency of readings really does make it better than competitors. But the fact that they can’t be bothered to add basic time and date functionality makes me wonder what else they are not doing. If it does know this basic thing, does it really know how to read radon levels? I hope so.
-- living in latvia, 2026-01-24

### *---- "Unclear App Origin"
Neither the physical manual nor the digital version linked from the QR code in the box include a link to this app. The manual says to install the "Ecosense RadonEye" app but this app does not have that name and the developer is some other 3rd party. It is therefore not clear this is the official app. Having to trust by comparing screenshots is poor practice for a device which sits in my home and connects INLINE through an app. The app itself looks like a developer's first ever written with no professional UI or UX consideration.
-- WheresTheQA, 2026-01-09

### **--- "App needs work"
App does not capture date and time. You cannot rename the device if you have more than one. Poor interface. 

All and all the app seems so poor that it does not give me confidence that the hardware works.
-- tsoglani, 2025-11-10

### *---- "No features"
App has no features . Very basic reading
-- ro goodwin, 2025-10-30

### **--- "Could Use A Tweak or Two"
The hardware seems to work however, the alerts can hardly be heard from the actual device.  In addition, when the alert goes off on the device, there is no notification sent to your iPhone to inform you.
-- tachyonbeam1, 2025-04-27

### *---- "App is garbage"
As many others have noted, there are no date and time stamps to the data meaning you have no way of knowing if there is a real health concern when limits are breached. Also, it does not alarm you when limits are breached despite setting the app to alarm you. I regret spending money on this device.
-- TonyB from MD, 2025-04-01

### ****- "Excellent monitor"
The best sensor at a reasonable price combined with a workable app. Unlike Airthings, this app / hardware combination doesn’t reliably choke on large downloads, it just works quietly in the background unless it detects an error and then it warns you.  

Could the app use some work? Yep, for example it could save / show the data in a format that includes time and date to make it more legible to humans. At the same time, it’s biggest use is determining whether a space is safe or not.  For that, it works exceedingly well (with the usual time delay of any sensor) and mitigation efforts should show up decisively, if effective.  

I used RadonEye to ensure that the repairs we did to the basement made effective reductions to absolute as well a average radon levels. For that task, it is perfect.
-- Irrational Exuberance, 2024-08-13

### *---- "Is the software even maintained?"
I’m shocked to find how few updates are made to this software that has bugs and simply not finished. No mater how good the device is (tbd) this software is the reason why it will be returned.  Again, shockingly poor execution.
-- N1KEZ, 2024-06-28

### **--- "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.
-- A.RoodAwakening, 2024-04-16

### *---- "Not downloading data"
When I go to the data tab and tap on refresh, it displays a progress bar and it gets stuck at 92%. Tried unplugging, reinstalling app.
