Free medical calculators for India — BMI, UIP vaccines, ObsCalc, drug doses, rabies ARV, CURB-65, NEWS2, GCS, Wells Score, Burn/Parkland, Neonatal Jaundice, Pediatric Asthma & more. Built by a doctor. No login. I built this because I kept getting frustrated during clinical work. Calculating things like: Growth percentiles Developmental milestones Rabies vaccination schedules …sounds simple, but in real life, it’s slow, error-prone, and honestly annoying.
