Your countdowns automatically sync between devices, including your Apple Watch. You can also AirDrop, text or email countdowns to your friends and family.
Make it yours
Customize
Use your own photos as a background, select a unique icon for each event and choose from eight time formats. You can even add animated effects, like falling snow.
Always in view
Widgets
Keep your countdowns on your Home Screen and Lock Screen. Pin a single event or show whatever is coming up next, then choose from nine widget styles and your own text color.
Just ask
Siri
“Hey Siri, how many days until Vacation in Days Since?” On iOS 27, Siri can also create, find, edit, open and delete countdowns, and it understands the countdown on your screen. Your countdowns show up in Spotlight, too.
Plan it together
Collaborate
Invite friends and family to follow the same countdown. Choose whether each person can view or edit it, and every change syncs to everyone through iCloud. Countdown history shows what changed and who changed it, so shared trips, anniversaries and family events stay on track.
