Fixed after deleting and reinstalling
This is one of my favorite apps. I use it all the time for work, and it is definitely a lifesaver. It was having issues after the last update and was crashing upon opening, but after deleting and reinstalling the app, it now works perfectly. Thank you MDCalc team for your assistance!

Excellent medical app, but iPad version with huge shortcomings
MDCalc is an excellent medical calculator, with updated literature citations and educational snippets. The iPhone version is stellar however the iPad version has several limitations in function that do not take advantage of the functionality of the iPad and it’s Pro-functionality.
I work on the wards and am frequently using many of the calculations in the App on my new iPad Pro with the magic keyboard. This means I am in landscape mode throughout the day.
Upon opening the app on landscape mode, the app does not rotate whatsoever. Meaning it cannot be used while the iPad is docked. The app also does not take advantage of the iPad OS’s multitasking features like split-view or slide-over, a huge detriment when I am charting on my virtual desktop app and looking to have MDCalc slide-over to briefly calculate a MELD score for example.
The addition of these features to the iPad app would make this a 5/5 app. But until then, it’s unusable for the iPad Pro especially when it is on the Magic Keyboard.
Thank you!! I have been waiting for this for a a long time. I used to use the website during my residency but the app was missing after explosion of smartphone devices. I really liked their layout and their explanation of the importance of a given calculator with links to reference articles.
