### 1/5 — Doesn’t work at all.

*2020-07-15, version 2.1.14*

It gives a low EMF reading EVERYWHERE! It doesn’t matter where i put it even next to outlets. I don’t recommend it at all. The only ones that actually work cost money that not everyone has sadly. Just don’t waste your time with this one.

### 1/5 — Horrible downgrade

*2016-07-18, version 1.0*

I used to love this app- great for "exploring", but now it won't stay open at all (as previously stated by several others). It makes me frustrated because I know it used to work very well! Please rectify this issue and I'll gladly rate higher and promote its use...
