S Health, originally announced alongside Samsung's latest premium smartphone in early May, is designed as a "personal wellness application" for Galaxy S3 owners.
Compatible with a number of healthcare sensors such as blood glucose meters, blood pressure monitors and body composition scales, the app collects health data and then creates graphs and tables showing a picture of the person's health.
S Health can track and chart health readings over prolonged periods, an important tool for people who need to monitor their conditions regularly.
Health measurement data from sensors can be transferred to the Galaxy S3 via Bluetooth or USB connection, or entered manually for sections including diet, exercise, medication intake and other criteria.
As Samsung feels that sharing health success stories is a key factor in boosting motivation, S Health is fully integrated with social networks, such as Twitter.
"S Health can provide real benefits in terms of tracking and monitoring health and wellness for our customers," said Simon Stanford, the vice president of telecoms and network at Samsung UK and Ireland.
"We're delighted to bring this innovative application to the Galaxy S3's portfolio of diverse content and applications to suit different needs."
S Health is available to download now through Samsung's More Services pre-loaded tool on the Galaxy S3.
The app is compatible with the following health sensor tools: Lifescan Blood Glucose Meter USB; OMRON Blood Pressure Monitor (HEM-7081-IT) and Body Composition (HBF-206-IT); and the A&D Blood Pressure Monitor (UA-767PBT-C) and Body Composition (UA-321PBT-C).
