### 5/5 — Absolutely must have for portable and easy to use sensors of all sorts

*2018-08-11, version 1.15*

I have the full set of sensors they make and the accuracy is really fantastic for such a small and simple set of adapters.

I highly recommend them for anyone who needs to do random testing of a variety of things from radiation to electrical current and more.

The interface is pretty basic and could use some enhancements and more capabilities.

### 1/5 — Doesn't work; always uses the wrong sensor display

*2016-12-08, version 1.9*

I have a UV meter device, but using the UV meter in the app always redirects me to the Geiger readout. As far as I can tell, the app is unusable with my device. This app is a piece of garbage; do not buy the devices associated with it.
