Requires always online, so server errors mean you cannot load your favourites / frequently used calculators quickly, nor can you use it in radiology suite with shielding. Nice interface, but always online pushes me to use MDCalc instead. Why this pocket calc needs to be always online remains a mystery.

Bad experience since they made the app require an active internet connection just to open. It's a pocket app and ideally should work even in areas with poor internet coverage. Will have to move to another app. What a shame.

Pretty good one thing that would be amazing and really easy to create is a conversion between metric and imperial measurements when you're doing BMI's eg input of imperial measurements, get BMI and also able to go back and see the conversion of height and weight in metric. PRE ASSESMENT NURSE HERE! Every second counts! Thanks!!
