About Atomic Clock
Display the exact time!
This app displays the exact time.
Birthday countdown, daylight saving time, or the New Year's Eve countdown, it doesn't get more accurate or simple than this.
Tip: Tap the clock for a distraction-free view.
Features:
- Automatic time synchronization via NTP
- Milliseconds display
- 24-hour and AM/PM modes
- Landscape and portrait orientation support
- Adjustable display refresh rate (lower values conserve battery)
- Date display with configurable format
- Keep screen on while the app is open
- Dark, light, and system theme support
- Custom NTP server support
For best accuracy, use the app on a stable internet connection. In areas with weak connectivity, the displayed time may be slightly off.
Technical information:
The time is fetched from NTP servers and requires an internet connection. Your phone's clock serves only as a reference — the accurate time always comes directly from the NTP server.
