Apple:

Apple today announced that customers in the US can enroll in three landmark health studies — the Apple Women’s Health Study, the Apple Heart and Movement Study, and the Apple Hearing Study. Conducted in partnership with leading academic and research institutions, these multi-year longitudinal studies are available in the new Research app, which can be downloaded today from the App Store.

Now participants can contribute to potentially groundbreaking medical discoveries with iPhone and Apple Watch, and help create the next generation of innovative health products.

This is yet another example of Apple’s efforts to further increase its lead and presence in the field of personal health. Sadly, it’s US only.
