Built for precise timing
Live HH:mm:ss display

System time
Exact Seconds uses your iPhone system time. For best accuracy, keep Set Automatically enabled.
Optional date
Show or hide the date in the main clock and choose its appearance in widgets.
No account
Open the app and use it immediately. No sign-in, subscription, or setup is required.
No ads
No advertising, IDFA, or cross-app tracking.
Why do seconds matter?
Exact-second visibility can help with time-sensitive online actions, scheduled windows, coordination, testing, and other moments when minutes are not enough.
Privacy
Exact Seconds does not require an account, show ads, or use advertising tracking. It uses limited PostHog product analytics only to measure whether configured widgets continue to be serviced by iOS over time.
The Widget Extension may send a widget_active event no more than once every seven days. The event includes a random persistent installation identifier, event timestamp, widget family, and the Widget Extension as the source. Exact Seconds does not send app-open events, widget colors, visual design choices, precise location, IDFA, or data for cross-app advertising.
