### 2/5 — Does “exactly” what it says

*2021-11-16*

Don’t expect any versatility here. This is INCREDIBLY limited in ability and application. I was wrongly hoping for more given that it’s a paid app. There are free tools online that are more capable, but I was aiming for an easier interface through an app. Oh well. Wasted a couple of bucks.

### 5/5 — Simple and accurate, Nice!

Great app, needs concentration/ml added. Also final concentration with a dilution factor.  Thanks
