About this app

Check server time and see how far your phone's clock differs. This NTP clock shows the selected time source beside the reading, with round-trip delay and details from repeated measurements. You can inspect the responses behind a sync before relying on the displayed seconds.

Search 712 built-in time sources by name or address, save favorites, or add up to 50 named sites of your own. The catalog includes NTP servers and web addresses. Website readings use the HTTP Date response as a reference at one-second resolution; they may differ from a site's internal booking or sales clock. Availability depends on the server and connection.

Keep the NTP clock beside a booking page in picture-in-picture on supported devices, or start a floating clock over other apps. Drag it out of the way and adjust its size, with separate opacity controls for the text and background. The floating clock requires permission to display over other apps and has a close button and a stop control in its notification.

Color signals mark clock times at 5, 10, 30 or 60-minute intervals. An optional warning appears during the last ten seconds before the hour. Choose sound or vibration when you want an audible or tactile cue. Signals work while a synchronized clock is visible and its time reading is fresh.

Save clock designs with your choice of colors, font and decimal display, including milliseconds. Picture-in-picture and the overlay can each use a different saved design. Displayed decimal places describe the format; accuracy depends on network conditions and the time source.

The NTP clock can refresh server time automatically about every two minutes while a clock is visible. Synchronization needs an internet connection and adjusts the time displayed in the app. Android's system clock settings remain separate.
