### 1/5 — Context please!

*2026-07-13, version 1.6.1*

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.

### 2/5 — Terrible app

*2026-04-30, version 1.6.1*

I cannot connect to cellular

### 2/5 — Does not provide time stamps

*2026-04-07, version 1.6.1*

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.

### 1/5 — App and unit aren’t connected long distance

*2026-04-02, version 1.6.1*

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.

### 5/5 — Great App that just works

*2026-03-05, version 1.6.1*

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.

### 2/5 — Great device with a useless app in terms of data tracking

*2026-01-24, version 1.6.1*

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.

### 5/5 — Works great

*2026-01-23, version 1.6.1*

Not sure why some people leave bad reviews. I plugged the device in, installed app, and Bluetooth connection was found in 1 second with an audible beep sound from the device. I go to sleep, next morning check app and see an average reading and under data tab I see 10 data points, 1 per hour it seems. This is exactly what I want from an app like this. No fuss 5/5

### 1/5 — Unclear App Origin

*2026-01-09, version 1.6.0*

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.

### 2/5 — App needs work

*2025-11-09, version 1.6.0*

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.

### 1/5 — No features

*2025-10-30, version 1.6.0*

App has no features . Very basic reading
