SAN FRANCISCO, CA (CBS) – The new Apple update will allow users to share some very intimate details with their iPhones.

A set of “HealthKit” features in the upcoming iOS 9 will allow users to track their reproductive health, including how often they have sex.

Apple says the health data is kept private by default, but a user can send it to his or her doctor or provide it anonymously for research.

The health app is part of an effort to create more software for female users.
