Important moments deserve more than a last-minute reminder. Moments Keeper brings birthdays, anniversaries, and everyday deadlines into one thoughtful place. See what is coming, plan ahead, and receive reminders at the times that work for you. BIRTHDAYS AND ANNIVERSARIES Keep important dates for family, friends, and partners together. Add a relationship, year, notes, and preparation tasks so the details you need are always close at hand. GREGORIAN AND CHINESE LUNAR DATES Record dates in the Gregorian or Chinese lunar calendar, including leap-month preferences. It is ideal for families who celebrate birthdays according to different calendar traditions. FLEXIBLE ADVANCE ALERTS Create several alerts for one event—for example, 30 days, 7 days, 1 day, and the day itself. Birthdays, anniversaries, and general reminders can each follow the schedule you choose. RECURRING REMINDERS Set one-time, daily, weekday, weekly, monthly, yearly, or custom recurrence. Organize document renewals, bills, health appointments, pet care, home maintenance, and more. HOME AND LOCK SCREEN WIDGETS See upcoming moments without opening the app. Home Screen and Lock Screen widgets keep the next important dates visible and link directly to their details. QUICK CONTACT IMPORT Use Apple’s contact picker to add a selected person and birthday. Moments Keeper reads only the contact you choose and does not upload your address book. PREPARE WITH CONTEXT Add tasks, gift history, photos, videos, or files to a reminder. On-device greeting ideas can help when you need a little inspiration. PRIVACY FIRST Your reminder data stays on your device. Face ID app lock, a privacy screen in the background, and hidden notification details help protect personal information. BACKUP AND RESTORE Export a complete backup to Files and restore it when needed, making device moves and long-term safekeeping easier. Moments Keeper has one purpose: help you remember early enough to show up thoughtfully.
