Register the first date with your partner, wedding anniversary, your child's birthday, or the day you first met your special person, and discover new anniversaries to celebrate. ■ Easy to view on iPhone calendar When activating the "Display in iOS calendar" option shown on the settings, the "Anniversary Reminder" calendar will be created on the iPhone calendar. You will never miss important birthdays and anniversaries as you manage them together with your daily schedule. ■ Notes We can't respond to reviews, so please contact our support team for issues or suggestions directly from the gear icon on the upper left corner of the app screen.
