Countdown
Read full descriptionHide full description
Countdown turns your calendars into a clear, bold countdown of the days left until every date that matters — work deadlines, birthdays, bills, trips and exams. • Big, glanceable numbers: "12 days", "Tomorrow", and hours and minutes on the final day. • A timeline drawn to scale, so busy weeks look busy. • Imports from Apple Calendar, Google, Exchange and Reminders — every event, only the calendars you pick, or just the ones matching keywords like "deadline", "birthday" or "exam". • Birthdays from your contacts, always the next one, with the age. • Categories and tags with their own colors, icons and reminder schedules. • Widgets for the Home Screen, Lock Screen, StandBy and Mac desktop, with a done button. • Live Activities count down the final hours on the Lock Screen and in the Dynamic Island — automatically on the day, or pin anything. • Siri and Shortcuts: "How many days until my next deadline?" • Syncs through your own iCloud. No accounts, no ads, no tracking. Try everything free for 7 days — nothing is charged automatically. Then unlock Countdown for life with one purchase, shared with your family through Family Sharing. In English and Spanish.
