If paying is hard, tap “Trouble paying?” for simple ways to pay with your Apple Account. • Premium can also be bought once, with no renewal. • If you cancel or leave without buying, one optional question asks what stopped you. One tap, anonymous, easy to skip. • New above the calendar: a one-tap “How are you today?” card to save your mood, and a small dot on the days you logged. • Another new card above the calendar helps you add your earlier periods. • Even if you tap “Not now”, reminders arrive quietly in Notification Center.
