### 5/5 — RN

*2016-03-30*

Very nice easy to the point!

### 3/5 — Looks good

*2014-09-03, version 2.0*

Seems to be a good app. Really missing a unit conversion functionality to switch to SI units. For this reason this app is of no use to me, and I'm sure many others around the world.

### 5/5 — Excellent!

*2014-03-30*

I. LOVE. THIS. APP. I use it when protocoling radiology exams and the few seconds it saves me on each exam that requires a GFR calculation really adds up when protocoling tens and tens and sometimes hundreds of exams. Very clean layout and expertly done. Love it!

### 5/5 — I use it all the time

*2013-12-27*

I use this almost every day!
