We’ve created a really fantastic animated GIF series to walk you through any questions you might have about our new app. While registering is hopefully straightforward, here it is on repeat:
Most of our calculators have one fairly straightforward results; we do our best to make the results clear and actionable, while still providing enough information to know why we’re saying what we’re saying. Sometimes though, equations have multiple results, because you might want different things. Dosing/fluid calculators are often this way. Take the Maintenance Fluids Calculator or the Sodium Correction Rate for Hyponatremia — each provides multiple results depending on what you, the clinician, need.
This obviously creates quite a challenge on such a small screen, so we’ve opted to provide you with what we hope is the most key piece of information for each score. And if you want more information, or there’s additional results? Just swipe up on the result panel:

It couldn’t be easier to get around the iPhone app from the Lists screen, your first view when you launch the app. Tap on one of the icons to access, or swipe left or right.
- A-Z (Full List of All Equations)
- My Specialty (Set by the specialty you choose on the Settings screen)
- Favorites (Set by tapping the star icon on list views or calculator pages)
- Recently Used (A running list created as you use the app)
It’s often a pain to be continually downloading a huge new app to your phone: you have to download the app, sync your phone, and often pay data fees. Since we’re constantly updating the site with more calculators and new content, we designed a system that will just download the new calculators and content to your app without having to download the entire app itself.
This should all happen automagically for you in the background — the app will check for new equations, and if it finds any, it’ll download them for you, as long as you have Wifi or cell signal.
If for some reason you’re having an error with any of your equations, you can always manually refresh all the calculators, by tapping the “Reload Calculators” button at the bottom of the settings screen. (If we did a good job, you’ll never need to use this button, but just in case, we wanted to include it.)

Did you forget your password? *Never fear!
We designed the app to keep users logged in on their phones so that you don’t need to be constantly logging in to an app that you, of course, use every single day — but if you do end up logging out and can’t remember your password, it’s really easy to make a new one.
Just tap the “Forgot Password” button on the app login screen.
- Enter your email address.
- Check your email for a message from firstname.lastname@example.org.
- Tap the link in the email to reset your password.
- Enter your new password (and remember it)!
- Go back to the app and enter your password.
- Voilà, you’re in!
*This is one of the few features that does require temporary internet access. Sorry! (Once you’re logged in you can be offline as long as you need. Your favorites will sync as soon as you regain internet access with the app open.)

We’re always happy to receive feedback from our users — one of the reasons we’re able to keep up with all the scores and calculators that modern medicine is producing is our users request them!
If you have an idea, question, comment, complaint, bug, error, problem, issue, or suggestion, we’d love to hear about it. You can tap the “Send Feedback” button in the app’s settings screen, or drop us a line on our app feedback page.

Most of us stick to the units we work with every day — in the US where we develop MDCalc, that’s US units — also known as |||. Almost everywhere else in the world, you use the frequently-more-sensible “SI Units,” short for the French Système International. (Fun fact: the Système International regulates units these units measure and decides just how much a kilogram weighs. And even more fun: the weights that SI used to use lost some of their weight over 100 years, so it’s now defined by a certain number of atoms.)
But I digress.
To change your units in the app:
- Go to Settings from the List view.
- Tap the units you’d like to use.
“But wait, I want to use kilograms in the US!” you say. No worries. Just like on the website, the three units of measure that are often used interchangeably can be changed manually by tapping on the unit itself. These are:
- weight (pounds ⇄ kilograms)
- height (feet/inches ⇄ centimenters)
- temperature (Fahrenheit ⇄ Celcius)
When you tap these, the number you enter will automatically convert to that number in the other unit.
For the visual learners out there:

Saving an equation is very simple from any list screen, or a calcuator page itself. Just tap the star next to the equation name.
To remove a favorite equation, simply tap the star again.

As MDCalc has grown, it’s become more and more unwieldy to simply “list all the equations on the site.” I mean, yes, we do offer a listing A-Z but it’s less and less useful to find something alphabetically now that we’re up to ≥175 equations. A couple solutions we’ve tried:
- Specialty and system categories were our first way of trying to organize all this information, but this is problematic as well, for a couple reasons:
What if you work in several specialties?
- What category do some of the disease calculators go into? Is a PE a cardiac phenomenon? A pulmonary one or a vascular one? Or maybe it’s a hematologic process? Or is it better for intensivists and hospitalists and emergency physicians to know about? But let’s not forget primary care, including family and internal medicine and OB-Gyn — they see plenty of patients with chest pain or unexplained shortness of breath. (Right now our policy is to try to find some “happy-medium” so that equations are categorized in the most common speciality and system categories, but not all of them. Please contact us if we’re missing any categories you’d like us to add or link up to a particular equation.)
- Some disease entities, medical problems, or clinical calculators don’t really fit into any system well. Where the heck does maintenance fluid rate go? Or mean arterial pressure?
So for our app we’ve developed a new system to help you, our over-worked, stressed, and under-appreciated users find what they’re looking for, as well as discover new related equations they might not be fully aware of or that we’ve recently added to the site.
You’re probably already familiar with “filters” if you’ve ever used shopping sites like Amazon or travel sites like Kayak. They allow you to “filter in” or “filter out” certain information to help you hone in what you’re looking for. Only “Non-stop” flights from “ORD” on “United.”
We’ve done the same, and incorporated tags into every calculator. You can think of tags as ways to filter equations. Currently you can filter using tags by these criteria:
- Chief Complaint
- Calculator Purpose (Diagnosis, Prognosis
And here’s an example of our filters in action:
