### 1/5 — Unusable app.

*2021-08-11, version 3949.01.20*

I purchased app because I liked the design for enteral formulas. There are no preloaded formulas on this app. Not sure how you sell an app that does not work.

### 5/5 — Excellent!

*2020-08-24, version 3949.01.20*

Excellent app! I use the PN calculator daily. 
Love the EN calculator as well! I would 100% to other RDs.

### 4/5 — Nice for on the go calculations!

*2020-02-03, version 3949.01.20*

Works great for simple calculations and analyzing PN formulations.  Appreciate the inclusion of osmolarity of final solutions.  Enteral calculator would be nicer if the major brands were preloaded into the app.
