Reminders
Notifications Set up reminders so you never miss a birthday Reminder Offsets Reminder offsets control how far before a birthday Cakeday alerts you, including on the day, 1 day before, 1 week before, and more. Learn how to configure them. Time Sensitive Notifications Time Sensitive notifications (iOS 15+) let important birthday alerts appear immediately and break through Focus and scheduled summary delivery. Birthday Alarm Birthday Alarm gives important same-day birthdays an alarm-style reminder, using Apple AlarmKit on iOS 26.0+ and Cakeday's fallback alarm on earlier iOS. Friend-Timezone Reminders Friend-Timezone Reminders make a birthday reminder follow the other person's local time instead of your current time zone. Learn how to enable it per friend. Communication Notifications Communication Notifications attach a friend's avatar and sender info so iOS shows Cakeday birthday reminders like a personal message from that person.
