What Physicians Are Saying
Used daily by doctors across 50+ countries in hospitals, clinics, and at the bedside
“ClinicalCalc Pro has become my go-to at the bedside. The GRACE and TIMI calculators alone have changed how I triage ACS patients.”
🇸🇦“The eGFR and KDIGO staging tools are incredibly accurate. I use them every ward round — saves me from mental arithmetic and reduces errors.”
“As an EM resident, having SOFA, qSOFA, and the Sepsis bundle all in one place is a game-changer. Fast, reliable, and evidence-based.”
“I recommended ClinicalCalc Pro to our entire neurology department. The NIHSS and stroke pathway tools are the best I've found online — free or paid.”
Super CalculatorsMulti-System Clinical Decision Support
Go beyond single scores. Super Calculators combine multiple validated tools into one comprehensive assessment — with guideline-based recommendations, organ-by-organ breakdowns, and treatment pathways.
qSOFA + SIRS + SOFA + Sepsis-3 with Hour-1 Bundle guidance
NIHSS + ASPECTS + tPA eligibility + thrombectomy criteria
TIMI + HEART + GRACE scores with cath lab activation criteria
RTS + ISS + TRISS survival probability with MTP activation
eGFR + KDIGO staging + KFRE risk + management pathways
TBSA + Parkland formula + Baux score + burn center criteria
Clinical WorkflowsStep-by-Step Decision Pathways
Don't just calculate — follow the full clinical pathway. Workflows chain multiple calculators together with evidence-based guidance, critical thresholds, and time targets at every step.
