About this app

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”

On my old phone, the app was useless, but when a new phone for a few days was good and now it is slow to respond when you search, it is not instant like the laptop version.

Was Very good app but with offline functionality gone now it is totally useless. If you can't make a good app then make it paid and hire some good developer for it.
