EchoCalc is the official App of the British Society of Echocardiography (BSE) made freely available to download. It contains all of the BSE normal reference values for transthoracic echocardiography and other widely used reference values, including those for prosthetic aortic and mitral valves. The information is displayed in an easy-to-use format, and is supported by clear high quality diagrams.

EchoCalc also includes a series of key echocardiography calculators commonly used in clinical practice:
- Body Surface Area (BSA)
- LV diameter indexed for BSA
- LV diastolic and systolic volumes indexed for BSA
- LV mass indexed for BSA
- E/Em for estimation of PCWP and diastolic function
- LA volume
- Aortic regurgitation: regurgitant volume, regurgitant fraction and EROA by volumetric analysis
- Aortic stenosis: aortic valve area by continuity equation and velocity ratio
- Mitral regurgitation: regurgitant volume, regurgitant fraction and EROA by volumetric analysis
- Mitral regurgitation: regurgitant volume and EROA by PISA
- Mitral stenosis: mitral valve area by pressure half-time
- Mitral stenosis: mitral valve area by PISA
- Prosthetic aortic & mitral valves: dimensionless index, EOA and EOA indexed for BSA
- Aortic root dimension indexed for BSA, age and sex of patient
