## Most critical reviews (10 lowest-rated)

### 1/5 — SERVER ERROR!!

*2024-07-27*

It says there is a server error!!!!!  This’s app DOES NOT WORK!!!!!

### 1/5 — SCAM

*2023-05-28*

You fill out the questionnaire and the it says “No Internet Connection.” Which is false with no help.

### 1/5 — App won’t open

*2022-10-18*

I’m having the same issue as everyone else. Too bad—I really enjoy their content.

### 1/5 — Trash!

*2022-08-01*

When you first open the app it prompts you to fill out a few questions. After doing so I click confirm and only get a message that says no internet connection. I just downloaded it with internet and every other app that requires internet is working. Only 3 bucks but it’s the principle.

### 1/5 — Not working

*2022-07-17*

Still not available to open after several removals and reinstall..

### 1/5 — No FUNCIONA

*2022-05-28*

Un engaño absoluto! Lo pagas y te da error de internet.

### 1/5 — No able to sign up

*2022-01-19*

It says no internet connection and I'm connected to internet. Without signup, it does not allow me to start the app. Waste of money.

### 1/5 — Login fail

*2021-10-21*

Fails to login (‚no internet connection‘)…

### 5/5 — Very useful

*2026-08-09*

This app works great both on and off the field. The quick, on-hand calculation tools are especially useful and really stand out.

### 5/5 — Great App

*2021-05-20, version 1.0*

This app is useful for all my perfusion and ecmo patients. Easy to use with useful information.
