Join the millions of medical professionals who use MDCalc daily to support clinical decision making at the bedside. Since 2005, MDCalc has been the leading medical reference for the most relevant, up-to-date and widely-used clinical calculators that support evidence-based patient care. Registration is free and takes less than 30 seconds for full, unlimited access.
MDCalc clinical decision support is created exclusively by board-certified physicians for use by physicians, physician assistants, nurse practitioners, pharmacists, and medical students. The simple yet sleek app provides access to 550+ easy-to-use clinical decision tools including risk scores, algorithms, equations, formulas, classifications, dosing calculators, and more.
With a new enhancement, clinicians can now earn AMA PRA Category 1TM CME credits by simply reading the clinical content for 150+ calculators. The app will keep track of the CME credits earned in a personal dashboard, where users can also redeem credits for certificates and access their receipts for easy documentation. In order to redeem CME credits, users will need to sign up for a paid CME plan.
Unique features, ideal for the busy practicing clinician:
• Works offline and in limited connection settings. (CME tracking requires a connection.)
• Fast and easy search and filter to discover new calculators.
• Customizable lists for quick access: favorites, recently used, your specialty.
• Auto-syncing between the website and app.
• Quick toggle between US and SI units.
• Error warnings and normal values to help avoid mistakes and improper inputs.
Our exclusive “MDCalc Method” for selecting tools - including in-depth appraisal and validation of evidence AND clinical relevance - results in only the highest-quality tools to help you make better decisions and be more efficient in your workflow. And our network of academic and practicing physician experts create easy-to-digest content to reinforce decision making and support training:
• Insights and advice from the EBM creators (e.g. Dr. Phil Wells’ on the Wells’ Criteria).
• Expert content by specialists on use cases, pearls & pitfalls, results interpretation and more.
• Synopses of the evidence from the original and validation research.
From iMedicalApps in 2016: “The evidence based medicine (EBM) components of the medical app are what really set MDCalc apart from its peers... The MDCalc app gives brief summaries of the critical studies concerning the medical calculator, links to the studies on PubMed as well as “pearls/pitfalls”, “next steps” and expert commentary from the authors of the calculators.” - iMedicalApps “MDCalc app, the best online medical calculator is now an app”

A must have
EM resident here. This app is one of the most powerful tools a resident has at their disposal. Most major scoring systems are utilized within it. I use it almost daily and cannot think of a more powerful tool than this!
On a side note: I wish some newer algorithms/scoring system is included in the future maybe with adding algorithms too? Great app though many thanks to the dev team👍🏻
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.
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!
