• When you log or edit a period, you can now choose its flow: Light, Medium or Heavy, on iPhone, iPad and Apple Watch. It's optional, doesn't change predictions, and Export Data includes it. • Apple Health: each logged period now appears as one entry, with its flow if you chose one, instead of an entry for each day. Entries synced by earlier versions are replaced automatically, so update the app on every device that syncs to Health. • Larger tap areas make calendar days, the calendar's buttons, Sort, the sharing actions and Restore Purchases easier to tap.
