SeClock vs Exact Seconds

SeClock shows just the seconds on your Lock Screen or Home Screen — the part the system clock leaves out. Long-press the Lock Screen or Home Screen to add the widget. An in-app purchase lets you tune the font, weight, size, and opacity so the seconds blend into your setup. Prefer the Dynamic Island? Tap the button in the app to start a Live Activity that keeps seconds ticking there for up to about 8 hours. You can also use the app itself as a fullscreen HH:MM:SS clock. *Widgets and Live Activities may be off by up to about 1 second.

Exact Seconds is a clean, focused clock that shows the current time down to the second. Use it when timing matters — coordinating a precise moment, checking the current second at a glance, or keeping an easy-to-read seconds clock on your iPhone. Features: • Large in-app clock with live seconds • Home Screen widgets with live seconds • Lock Screen widget with live seconds • CarPlay widget support • Multiple widget sizes • Widget appearance themes and color options • Stable HH:mm:ss time format • 12-hour, 24-hour, or system time format in the app • Multiple in-app clock colors • Black or white in-app background • Optional in-app date display • No account required • No ads • No advertising or cross-app tracking The main app gives you a customizable full-screen seconds clock. Widgets provide quick access to exact time on the Home Screen, Lock Screen, and supported CarPlay displays. Exact Seconds uses your iPhone system time.

This analytics does not use IDFA and is not used for advertising or cross-app tracking.
