## Most critical reviews (4 lowest-rated)

### 1/5 — Says Apple watch app included

*2020-11-29*

I'm not sure what your supposed to put in the fields, but the way it is described, if you have an apple watch, the app will tell you your qt interval when you do an ecg. What a waste of time and money.

### 3/5 — Too advanced for lay folk

*2020-06-24*

I just don't know what is good or bad.  Seems convenient.  But it is beyond my grssp and I have four college degrees, hustt not iin anything about medicing.

### 5/5 — Sehr toll

*2022-11-18, version 5.0*

Finde die App wunderbar. Medizinisch bestmöglich. 

Wünschenswert wäre natürlich eine Integration mit Apple Watch. Das kann ich aber natürlich bei einer Gratis App nicht verlangen. 

Also volle ⭐️⭐️⭐️⭐️⭐️

### 5/5 — Der beste QTc-Rechner im Store

*2019-01-25, version 2.1*

Schnell, bedient sich super, funktioniert top.
