Q. With all the medical calculators out there, can you recommend an app that keeps them all in one place?

Calculate by OcMD is a handy free app which keeps all your medical calculators in the one place. Available for both iOS and Android, it contains more than 200 unique calculators and decision support tools. The calculators are organised into a number of categories:

• Guide treatment calculators like the cardiovascular risk scores like the Framingham or the CHA2DS2-VASc for atrial fibrillation treatments
• Prognostic calculators – used in heart failure and chronic kidney disease
• General calculators – ideal body weight, Due date and gestational age
• Classification – angina (CCS), congestive heart failure (NYHA)
• Screening – diabetes, breast cancer
• Management calculators – Ottawa ankle injuries and TIAs Diagnostic calculators – sleep disorders (Epworth sleepi-ness scale).

From the same developers as Pedi STAT, it is an excellent reference for caring for paediatric patients in the critical care environment.
