About this app

Is your phone's clock really right? Atomic Clock shows you the exact time, synchronized with internet time servers, and tells you how many milliseconds your phone is off.

Use it to catch the start of a ticket sale or a limited drop, to bid at the last second, to set your watch, or to count down to midnight on New Year's Eve. Or simply as a beautiful clock on your desk or nightstand.

EXACT
• Synchronized with time servers that follow atomic clocks
• Several measurements per sync, the most precise one wins
• Shows the accuracy of each sync, e.g. "±8 ms"
• Compensates the delay of your screen
• Keeps counting exactly between syncs, even if the phone's clock is changed

BEAUTIFUL
• Digital or analog, with 10 dials, including a railway station clock
• Over 20 fonts, including a classic 7-segment display
• Your own colors for digits, background and hands
• Glowing digits, blinking colons, a second hand that ticks or sweeps

AUDIBLE
• A tick every second
• Time signal like on the radio: beeps from second 55, long beep on the full minute
• Spoken time or a chime every few seconds or minutes

MADE FOR ALWAYS ON
• Screen stays on while the clock is open
• Burn-in protection gently moves the display
• One tap hides everything but the clock
• Portrait, landscape, any time zone, dark or light

Needs an internet connection to synchronize. No account, no setup: open it and see the exact time.

Ratings and reviews

Unfortunately, this app does not have a setting to choose 2-digit milliseconds. The only option is Show milliseconds, which displays 3 digits.

accurate - easy to read - easy to setup - use all the time as a main source of accurate time.

Great App for when you really want to know PRECISELY what time it is, to set your watch to the exact second, for instance. Simple yet very useful.
