AtomicClock helps you set watches, wall clocks, cameras, and other devices, compare local time with UTC, and follow moments when every second matters.\n\nClear analog and digital time\nAtomicClock displays current time from NTP servers that reference atomic clocks. Choose a predefined server or add your own, then view local or UTC time in a clean analog or digital clock.\n\nCustomize your reference clock\n• Switch between 12-hour and 24-hour time\n• Customize the time format\n• Choose from multiple clock faces and hands\n• Use a smooth, fluid second hand\n• Add acoustic ticking or the Greenwich Time Signal\n• Tap the screen to hide information and controls, freeze the display, or mute ticking\n\nDetails for precise time checks\nView technical NTP information, including round-trip time and server stratum. Whether you are checking a timestamp, preparing a camera, aligning a wall clock, or setting a watch by hand, the seconds remain clear and easy to follow.\n\nAtomicClock is free to use. AtomicClock Pro is available as a one-time purchase with no subscription. It unlocks your preferred clock face, hands, and font, removes ads, and includes upcoming Pro features.\n\nAtomicClock displays NTP reference time for comparison and does not change your device’s system time. Results can vary with the selected server, network conditions, and device behavior.","facts":{"developer_id":1387413672,"developer_url":"https://atomicclock.app/","first_released":"2018-07-25T09:57:34Z","support_url":"https://atomicclock.app/","privacy_url":"https://atomicclock.app/privacypolicy","website_url":"https://atomicclock.app/","app_version":"3.6.25","release_notes":"• Improved app reliability and compatibility with latest platform components\n• General performance and stability improvements","rating_current_version":4.8158,"rating_count_current_version":5570,"star_counts":[68,32,96,466,4906],"genres":["Utilities"],"languages":["SQ","AR","BG","CS","DA","NL","EN","FR","DE","HE","HU","ID","IT","JA","KO","LT","PL","PT","RO","RU","ZH","ES","SV","ZH","TR","UK","VI"],"content_advisories":null,"device_families":["iphone","ipad","ipod"],"chart":null},"freshness":{"apple_read_at":"2026-10-21T03:36:12.818Z","catalog_read_at":"2026-10-19T10:40:11.798Z","reviews_checked_at":null,"summary_written_at":"2026-10-20T07:09:11.605Z","placed_at":"2026-10-17T07:19:13.393Z","scored_at":"2026-10-21T05:05:13.887Z"},"editorial":{"one_liner":"Shows NTP reference time from selectable servers in analog or digital clock faces, with local time and UTC views.","what_is":"AtomicClock displays current time from NTP servers that reference atomic clocks, using a predefined server or one you add.
