### 5/5 — Simple & straightforward

*2023-02-18*

This app is for surgeons to determine 30-day risk of operative mortality and morbidity. It’s an AI algorithm that has been externally validated in most patient populations and is apparently more reliable than other current estimators, including the ubiquitous NSQIP calculator. The app is straightforward, easy to use and does exactly what it says with few frills.

### 1/5 — Not compatible with iOS 15??
