Im a resident and use this app every day on rounds. Its easy to use, easy to search, and has explanations for the formulas and interpretations as well. If youve used mdcalc.com, then get this app and youll never need that website again. Totally worth it. Not sure what others are complaining about, the upgrade worked fine for me and was of course free.
I love the different options it has. From putting in an ABG and getting up to 3 concurrent interpretations of processes to being reminded of GCS or CAM-ICU to correcting calcium for albumin, it helps keep you accurate for presentations. Id highly recommend it.
