### 1/5 — This app is worse

*2018-02-01*

Than their other app.

### 1/5 — Crashes immediately

*2017-08-11*

Useless, can't monitor from phone, have to look at actual device, defeats the purpose of getting this unit

### 4/5 — Works ok

*2019-06-22*

It is working with radon eye rd200 iphone 7 ios 12. It is very simple app needs more features .

### 4/5 — Works ok, simple app

*2019-05-17*

Connected first time (seems to be Bluetooth, direct connection from app). Syncs logged data, graphs it. Interested to monitor radon over time. Would be nice if it also allowed phone alerts vs device alerts but BT's 10m range probably makes that less useful...
