Remember every day that matters — and get reminded before it arrives Countdowns and anniversaries, both in one place. A friend's birthday, the day you got together, the day you brought the cat home, the day you got the keys to your own place, the day your baby took their first steps, the exam coming up. Write them all down. Get reminded on the day, or however many days early you like. Enter it once — the app builds both the countdown and the anniversary The home screen answers "how long until", the Memories page answers "how far you've come". Add "Together" and the home screen counts down to your 2nd anniversary, while Memories shows "1 year 3 months so far". Add a birthday and the home screen counts down to turning 18, while Memories shows "17 years 9 months so far". Seven themes, pick the one you like Seven palettes — cards, buttons, filter chips and page background all change together, not just an accent color. For backgrounds, use the built-in patterns, a solid color, or your own photo. Day books Sort your days into books: family, love, work, travel… pick the color and icon yourself. The lunar calendar, done properly Lunar birthdays and traditional festivals land correctly year after year, leap months included. Born on the 30th of the last lunar month? In years without a 30th, you'll be reminded on New Year's Eve. Real holiday rules for dozens of countries and regions Including the Chinese mainland, Hong Kong, Taiwan, Japan, Korea, Singapore, Malaysia, the US, Canada, the UK, Germany, France, Australia and many more — using each region's real make-up-day logic, with a badge telling you whether that day is actually off. Widgets in several styles Home Screen and Lock Screen widgets recalculate at midnight, so the number you glance at is the right one. Several sizes and styles. Also • Turn any day into a shareable card, in several styles • Retirement countdown, with a progress bar • Pick your own units — days, weeks, months, years, or any combination • Choose how many days ahead to be reminded, and at what time • Anniversaries and milestones (100 days, 520, 1000…) • A trash can, so a mis-tap isn't the end • Lock the app with Face ID Privacy first Everything runs on your device.
