Event Days Timer
Persist. Await. Never forget. — Add once—auto-sort into elapsed, countdown, or recurring. Custom units, system alarms, widgets, and optional iCloud sync.
We will add a direct App Store button here once the app is published.
Highlights
“How long since” and “how long until” in one place.
Events land in Elapsed, Countdown, or Recurring by time and repeat rules—countdowns move to Elapsed when due.
Toggle year through minute per event; seconds (and milliseconds in Precise mode) always show, with roll-down conversion.
Optional AlarmKit / system-level alarms; after a device change you may need to re-authorize.
Events and groups sync via your Apple ID’s private iCloud Drive—not third-party servers.
Multiple widget layouts for upcoming moments, plus a theme library for list and widget styles.
Choose calendar type when editing; yearly, monthly, weekly, daily, or custom intervals.
Organize with groups and name filters—up to about 500 events, with efficient live updates.
No first-party account, no ad tracking—data stays on-device and optional Apple iCloud.
