Live Countdown Widget on iPhone: How to Get Seconds Ticking
Short answer: a normal Home Screen or Lock Screen widget cannot stay live for days; iOS redraws widgets on a schedule, so they show whole days. For a countdown that ticks by the second, start a Live Activity in an app that supports one. It appears on the Lock Screen and, on iPhone 14 Pro and later, in the Dynamic Island. Two popular countdown apps list one: Countdown: Event Countdown and DayDrop.
One nuance: iOS does allow a timer-style text inside a widget that ticks on its own. DayDrop uses it so its widgets show hours, minutes and seconds in the final 24 hours before an event with a set time. Most countdown apps don't.
Widgets and Live Activities are different things
| Widget | Live Activity | |
|---|---|---|
| Where | Home Screen, Lock Screen, StandBy | Lock Screen and Dynamic Island |
| How it updates | iOS redraws it on a schedule from a timeline the app supplies; limited refreshes per day | iOS renders a live timer from a start and end time; the app can push updates |
| Can it tick seconds? | Only via a timer-style text, which few apps use; otherwise no | Yes, continuously |
| How long it lasts | Permanent until you remove it | Ends after 8 hours (the app must start a new one); lingers on the Lock Screen up to 4 hours after ending |
| Best for | "42 days to Lisbon" at a glance | The last day, the last hour, the last ten seconds |
So the honest setup is both: a widget for the long view, a Live Activity when the event is close. Apps that know this show days in the Live Activity for far-off events and switch to a ticking clock as the moment approaches; DayDrop also fills a progress ring as the day gets closer.
How to start a live countdown (iOS 18 and iOS 26)
Install an app whose listing includes a Live Activity or Dynamic Island countdown. DayDrop and Countdown: Event Countdown both do.
Create the event and set a time, not just a date. A countdown can only tick to an exact moment.
Open the event and tap Go Live (DayDrop) or the app's Live Activity button. In DayDrop the Live Activity is a Premium feature; the yearly plan has a one-month free trial.
Lock the phone. The countdown ticks on the Lock Screen. On iPhone 14 Pro and later it also sits in the Dynamic Island; press and hold it for the expanded view with the progress ring.
Nothing showing? Check Settings → the app → Live Activities is on, and Settings → Face ID & Passcode → Live Activities is on so it appears on the Lock Screen.
Why Apple built it this way
A widget that redrew every second would keep the display pipeline busy for every widget on every Home Screen, so iOS gives each widget a daily budget of refreshes based on how often you look at it. A Live Activity is the sanctioned way to show something changing in real time: iOS itself draws the timer from a start and end time, the app doesn't run in the background to tick it, and the 8-hour cap stops a forgotten activity from living forever. That is also why a countdown Live Activity for an event three weeks away shows days rather than a 500-hour clock.

Why doesn't my iPhone countdown widget tick down by the second?
Widgets are snapshots iOS redraws on a schedule, so they show whole days. iOS allows a timer-style text inside a widget (DayDrop uses it for the final 24 hours), but most apps don't. For a continuous tick, use a Live Activity.
What is a Live Activity?
The real-time element iOS uses for scores, deliveries and timers. It shows on the Lock Screen and, on iPhone 14 Pro and later, in the Dynamic Island, and can tick by the second. It ends after 8 hours (the app then has to start a new one) and lingers on the Lock Screen up to 4 hours after ending.
Which countdown apps have a Live Activity?
As of October 2026, Countdown: Event Countdown by ROOT38 and DayDrop describe one in their listings. Most countdown apps offer widgets only.
Does a live countdown drain the battery?
Very little. iOS renders the timer from a start and end time; the app doesn't run to tick it.
Can a Live Activity count down for weeks?
Not continuously, because of the 8-hour limit. Apps show days for far-off events and switch to a ticking clock in the last day.
My widget is stuck on the wrong number of days.
That's a refresh problem, not a feature gap: see Countdown widget not updating on iPhone: 7 fixes.
