Full description
Need the exact time to set a watch, align a wall clock, compare UTC, or catch a moment where seconds matter? AtomicClock shows precise reference time from NTP time servers in a clear analog or digital clock. NTP servers provide network time referenced to atomic clocks. Choose a predefined or custom time server, then view local time or a UTC clock in 12-hour or 24-hour format. Use AtomicClock as an NTP clock, precision clock, reference clock, or seconds clock for manual time checks. Practical ways to use AtomicClock • Set a watch, wall clock, camera, or other device manually • Compare local time with UTC • Check precise time before an event or scheduled task • Keep a clear clock visible while you work using picture-in-picture with Pro Clock display and signal options • Analog clock and digital clock views • Custom time formats, clock faces, hands, and fonts • Smooth, fluid second-hand movement • Optional acoustic ticking sounds • Greenwich Time Signal • Home screen clock widget with time and date • Tap actions to hide information, freeze the display, or mute ticking For technical NTP checks, view details such as the selected time server, round-trip time, and stratum. Accuracy depends on the server, network conditions, and device behavior. AtomicClock is designed for reference time and manual clock sync. It does not automatically change device system time. The home screen widget uses system time for technical and battery reasons. AtomicClock is free to use. AtomicClock Pro adds preferred clock styles and fonts, many widget customization options, all tap actions, picture-in-picture, and ad removal. Pro is a one-time purchase through your Google Play account with no subscription.

What's new
