DueStack
Countdowns on Lock Screen
Free · Designed for iPad. Not verified for macOS.
Pin important dates to your Lock Screen and Dynamic Island, then open the exact countdown when it matters.
DueStack keeps the dates that matter most visible, so important deadlines are never buried in a calendar.
Create countdowns for paper submissions, trips, birthdays, anniversaries, subscription renewals, ticket drops, and the dates you cannot afford to miss. Pin the most important events to your Lock Screen and Dynamic Island with Live Activities, then tap any countdown to jump straight back to its detail page.
Features:
- Track upcoming deadlines, events, birthdays, anniversaries, and renewals
- Pin countdowns to the Lock Screen with Live Activities
- See glanceable countdowns in Dynamic Island and Lock Screen widgets
- Open a pinned countdown directly from the system surface
- Use count-up mode for past events and yearly recurring birthdays or anniversaries
- Sync privately across your devices with iCloud and CloudKit
DueStack does not require an account with us, does not use advertising trackers, and does not send your countdown data to our servers.
