Apple has published the first details of an ongoing Apple Women’s Health Study, using the iPhone to carry out longitudinal research on menstruation.

The project, which involves a team from Harvard T.H. Chan School of Public Health, is based on data from 10,000 participants across the U.S. Users have been contributing their data using Apple’s Research app, starting late last year.

Whether it’s heart health or exercise routines, there are plenty of biometrics Apple Watch can keep tabs on. But could it also be used to monitor cognitive performance and possible decline?

That’s the basis of a new, multi-year observational research study announced Monday. A collaboration between Apple and neuroscience company Biogen, the aim is to assess the role the Apple wearable and the iPhone could play in measuring cognitive health.

Apple Research, an application that lets users take part in groundbreaking medical studies, scored an update today to let participants share data from their AirPods Pro with the Apple Hearing Study. A new version of the associated Apple Watch app also promises battery life improvements.

This week we get healthy with Apple’s Research app, build ridiculously-powerful shortcuts with Toolbox Pro, listen to internet radio with Triode, and scare ourselves silly with Layers of Fear. Shiver.

Apple today unveiled its brand-new Research app for iPhone, with three new health studies for users in the United States.

The Apple Women’s Health Study, the Apple Heart and Movement Study, and the Apple Hearing Study are available from today. They give participants the opportunity to contribute to “groundbreaking medical discoveries with iPhone and Apple Watch.”
