This tool shows you the ultimate precise time of day. To achieve this, it uses a special internet time protocol to fetch the time from an atomic time server. We are proud to offer version 5 of the Gorgy Timing Atomic Clock. The program is one of the classic applications since the early days of the Apple App Store and has been continually improved based on user feedback. The Gorgy Timing Atomic Clock shows the precise time of day. To achieve this, it uses a special internet time protocol to fetch the ultimate precise time from cesium atomic clocks available on the internet, or any other time server you like. The graphical display mimics the clock display of the legendary Gorgy Timing clocks, which are used in professional radio and television studios, and we spent much effort to bring the original feeling of these wickedly expensive clocks to your iPhone. This app is used by BBC studios, astronomers, concert promoters, etc. Version 5 contains the following functions: * Universal support for all iPhone, iPad and iPod touch devices running iOS 8 or higher (including iPhone 8, iPhone 8 Plus, iPhone X) * Optimized for iOS 11, full 64 bit support * Alarm function with snooze (touch anywhere on the screen), volume fade-in, based on weekdays * Alarm time based on seconds (not minutes) * Alarm notification window instead of normal alarm sound, if app is not running or in the background * Use playlists or a manual picker selection from your own music library as alarm sounds * The alarm sound is also playing when the device is muted, or the display is switched off, and also works in AirPlay environments * Customizable time server sources * Colors: green, red, blue, yellow, white, hidden, with a separate color option for digits, seconds and segments * Alternative visual display of fractional seconds (1/60th sec. resolution) * 12/24 hours display * Optional second tick sound * Full landscape support (including settings dialog) * Touching the display lets the buttons and status bar fade out * Touching the display again will add the current date (in all orientations) * Disabled screen auto-lock * Options "sync at startup", "hourly", "daily", or a sync button for manual syncing * The last known time delta is used when started without sync * "Night mode", which dims the display using a slider, shows the seconds with only one dot (to prevent a hard brightness switch between second 59 and second 0), switches off the tick sound, and reduces screen updates to save battery * To minimize burn-in effects (especially on the iPhone X OLED display), the clock is doing micro movements when running longer than 5 minutes * VoiceOver support Answers to common questions: * An application can not set your device's system time, so a time sync between the atomic time and the device time is not possible. * If you want to wakeup with music, please do not exit the app before going to sleep (which would result in a local notification dialog without music in the morning), but let it run with the display switched off. This application's music alarm, and this is not common, will still work when you switched off the display, even in battery mode. But be aware that running an application all the time, even without display, consumes battery, so please make sure that your iPhone is fully charged before you go to bed, or even better, connect it to your charger.



  • Accurate

    This app is a visual and audible true NTP time server, on the order of 1/10 second. There are several “atomic” time apps that do not repeat NTP time. (Always test and check the output of any time app.)
  • I’ve been using it for years

    I’ve never been disappointed. Great app!
  • Perfect. Gorgeous. Accurate.

    Impossible to improve, but they keep doing it anyway. Beautiful, elegant design and perfect time.
  • Ultimate Atomic Time App

    By Jim92677
    Considering the number of configurable features and the exceptional support from the developer in regards to answering user questions and adding new support, this app is the ultimate atomic time app. It is simple and elegant. I use this app to check the accuracy of watches and clocks. I also use the app as an amateur astronomer. Thanks the exceptional app and ongoing support.
  • A horological neatness

    By mcsandberg
    I use this to set an ancient french carriage clock, a Seth Thomas and a cuckoo clock. Its the only app I’ve found that displays a large format with seconds.
  • No sound!

    By Superjohnh
    I’ve use this app for as long as I’ve had iPhones and it works well. Just do the latest update, and there is no audio no way for me to turn it on even with the volume on full. I have an iPhone X with 11.2.5 iOS. What’s wrong? UPDATE: If I switch it from digital to analog mode the sound comes on.
  • Great App!

  • Great App

    By wolfbyte
    I love this app, but I have a question: The information says that the app can be added to the Apple Watch, but I see nothing that tells how to do it. Please tell me how to do it. I tried to contact the support department but could not get through.

    Not the same display on the watch as on the iPhone. Watch only shows hour and minute in small digits in corner and seconds in large center. No options on watch. Disappointed. Wasted my 2 bucks.
  • Can't Reach timeserver

    By Delosla
    Get an error message that states that a network is available however can't reach timeserver possibly due to a firewall. Tried all of the available time servers and have also tried a wifi and LTE cellular connections. Been able to connect to a time server since October. iPhone 6S plus iOS 10.3.3. Any ideas? Thanks..
