Apple is making a bid for its customers' healthcare data by launching a new "Research app" which will collect information from iPhone and Apple Watch users and share it with academic studies.
The app is being pitched to Apple's estimated billion customers as a way to "contribute to groundbreaking research studies".
It is an opt-in programme which will share the data captured by Apple's existing monitoring of users' menstrual cycles, electrocardiogram sensoring, as well as a decibel measure to analyse the noise of the environment.
