### 4/5 — Great medical calc

*2024-07-04, version 5.2*

Easy and quick to use. Unfortunately, it doesn’t seem to be getting any updates, and a couple calculators don’t work: the age calc won’t let you input a birth year, and the temp conversion calc only converts to C. There are other apps for that stuff, though, and important calculators I’ve tried all work.

### 4/5 — App útil

*2023-07-11, version 5.2*

Aplicación útil en el ejercicio de la profesión

### 4/5 — Good but could have more

*2021-05-09, version 5.2*

It would be nice if the 4T score for HIT was added.

### 5/5 — Strumento di lavoro imprescindibile

*2018-10-22, version 4.6*

Come da titolo

### 2/5 — Infusion calculator

*2017-02-28, version 4.6*

Was an excellent app until one day the infusion calculator (IV RATE) was removed along with all my saved medications and notes. Just gone...  So upset. Now it's just an app with a few useful calculators but it lost its edge it has over the others

### 4/5 — Shock Index and Nice APP

*2016-09-24, version 4.6*

Nice APP would like to see shock index added to the formulas.

### 2/5 — A Dean

*2016-02-15, version 4.5*

The carboplatin calculator appears to be missing

### 1/5 — Dosis pediatricas

*2016-01-15, version 4.5*

Con la actuación se eliminaron las dosis pediátricas. Perdí con eso mucha información. Arreglen esto
