### 5/5 — A skeptic review

*2021-10-18*

So I was skeptic that it works based on the reviews. The bad reviews boil down to operator error and not understanding the formulas. So I downloaded and tested the app to check validity. 

The formulas I used were:

Pulse pressure (PP) = SBP - DBP
MAP = DBP - 1/3PP

If you do the math on various blood pressures the math checks out and works as expected. The app does the same rounding a person would by hand of .5 goes up and .4 and below stays the same. Don’t believe the bad reviews from a lack of understanding the actual math equations to get these numbers. If you don’t believe me try for yourself. I mean the app is free. See for yourself. 

(Disclosure: I am not financially or benefiting in any form from my positive review. Just an ems guy who was looking for a calculator to do the math for me. Saw some bad reviews, and tested it myself to see if it was a trash app or not. )

Hoping this review helps the next guy looking for a MAP calculator.

### 1/5 — Incorrect

*2020-02-09*

The results are incorrect. Way low for what it should be.

### 5/5 — Finally!!

*2019-08-25*

Finally what we were looking for in EMS!!

### 5/5 — Does exactly what it says!

*2019-07-03*

Quickly converts systolic and diastolic blood pressure values to a mean arterial pressure as advertised. Not sure why other reviewers sound confused as to how it works... probably operator error.

### 1/5 — Doesn’t do anything

*2018-10-12*

There is no information about how this work. The app either on the Apple Watch or in the iPhone don’t show anything to calculate the blood pressure.
