Description
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.
Recent changes: - Added theme setting: Dark (default), Light, System - Added option to keep screen on - Added configurable date format - Added custom NTP server support - Fixed last sync time showing device time instead of NTP-corrected time
