MDCalc Medical Calculator

Looking for a Clinical Decision Support Tool That Works Offline?

MDCalc Medical Calculator delivers over 550 evidence-based clinical scoring tools, dosing calculators, and algorithms directly to your mobile device. Designed for physicians, nurse practitioners, and other healthcare professionals, this platform supports real-time clinical decision-making at the point of care. With no advertisements in the free version and a Turbo subscription option for advanced features, the app aims to reduce cognitive load during patient encounters.

Core Functionality and Clinical Tools

The application provides unrestricted, free access to a comprehensive library of clinical calculators, including risk stratification scores, diagnostic criteria, and drug dosage guides. Each tool is curated through the MDCalc methodology, which involves a rigorous selection process to ensure only the most reliable and clinically relevant instruments are included. The content is developed and reviewed by specialists across multiple medical disciplines, with supporting materials such as quick-reference summaries and evidence briefs to explain the rationale behind each calculation.

For users pursuing continuing medical education (CME), the app integrates a credit-earning system. By reviewing clinical content associated with over 150 calculators, you can accumulate AMA PRA Category 1 Credits™. A personal dashboard tracks your progress, and credit redemption requires a paid CME plan. Note that internet connectivity is necessary for CME tracking, but the core calculator functionality works offline.

Key Operational Features

• Offline access to all 550+ clinical calculators – No internet connection required for core functionality, making it usable in hospital basements, rural clinics, or during flight.
• Customizable specialty lists – Create personalized folders of your most-used tools for one-tap access during fast-paced clinical workflows.
• Automatic unit conversion – Supports international medical practice by converting between metric and imperial units, with normal range indicators and input error warnings to prevent miscalculations.

Expanded Tool Library by Specialty

The app covers a broad spectrum of medical fields, from cardiology to urology. Commonly used calculators include the Creatinine Clearance (CrCl) formula for renal function, the CHA2DS2-VASc score for atrial fibrillation stroke risk, the MELD Score for liver transplant prioritization, and the Wells Criteria for pulmonary embolism diagnosis. Many of these tools are also eligible for CME credits, allowing you to earn while you calculate. The library continues to expand with each update, reflecting current guidelines and emerging evidence.

Advanced Features via Turbo Subscription

While the base app is free and ad-free, the Turbo subscription unlocks additional capabilities. These include enhanced offline synchronization between mobile and web platforms, priority access to new calculator releases, and an ad-free experience across all devices. The subscription also supports more detailed CME tracking and reporting features for institutional use.

Technical Considerations

The app is optimized for quick navigation, with a search function that finds tools by name, specialty, or keyword. Input fields are designed for single-handed operation, with large touch targets and clear labeling. The dashboard provides a history of recent calculations, allowing you to review past results without re-entering data. For international users, the app supports multiple languages for interface elements, though clinical content remains in English to maintain medical accuracy.
