Apple has just launched a new health platform called HealthKit, designed to bring together all of its users' health and fitness metrics into the one app.

There are already more than 40,000 health apps and devices monitoring everything from activity levels and sleep quality to weight control. Apple's new Health application will pull in data from third-party apps and consolidate them into one health profile.

The initiative works with companies like Nike to bring all your health information into one place and enables customisation of the stats you want tracked and how you want it presented.

Beyond exercise applications, HealthKit is working with health care providers to provide up-to-date information on patient vitals in real time so that users can share health information with their doctors.

The new HealthKit, which will be released in September, could potentially interact with wearable devices like Apple's much-anticipated iWatch.
