# AtomicClock

> AtomicClock is a precision clock app that displays reference time from selectable NTP time servers.

AtomicClock shows precise current time in analog and digital clock views. It is useful for checking exact time, comparing local time with UTC, manually setting watches, wall clocks, cameras, or other devices, and timing moments where seconds matter. The app can use predefined or custom NTP time servers and can show technical NTP details such as round-trip time and stratum. AtomicClock displays reference time from NTP servers; it is not a physical atomic clock, and accuracy depends on the selected server, network conditions, and device behavior. Some advanced features require AtomicClock Pro, a one-time purchase with no subscription.
