### 5/5 — Reassuring

*2016-01-21, version 0.9.11*

I'm getting about one count per twenty minutes of measuring. Just enough to let me know the hardware is doing something, and the background radiation at my place is quite low.

### 5/5 — Bring the Sound Alert Ticker

*2015-12-18, version 0.9.10*

Please add the Sound Alert Ticker to be able to hear the counts, great app, but needs the sound.

### 4/5 — Good app.

*2015-05-01, version 0.9.3*

Simple and easy to use. 

Snap shots need more info.
