### 4/5 — Additional meds

*2025-10-12*

Nice app but on your next update could u add ketamine

### 4/5 — Additional meds

*2023-08-08*

Nice app but on your next update could u add ketamine

### 2/5 — Not enough

*2017-08-21*

Kind of a waste, wish you could adjust the ranges of the drugs. Different areas/countries use different ranges. Otherwise a good concept.

### 1/5 — Waste of $

*2016-01-26*

Only has the drugs shown in example.

### 1/5 — Don't waist your $

*2015-12-20*

The two screens you see are the only 2 you get. Only the drugs on the first page. You can't add or delete to customize for local protocols.

### 1/5 — Not Good

*2013-10-24*

Most people in the US do not know their weight in kg.  Also very limited med selection.

### 1/5 — Don't buy

*2013-02-20*

Not what you think. What you see is what you buy. Unable to input any other drugs than what you see. Poor program.

### 1/5 — Inadequate

*2012-09-23*

This app gives you no choices in drugs displayed, and has a very short list of meds at best.  Needs a lot of development and is way overpriced
