Big Clock is designed specifically for iOS users. With an optimised layout for iOS devices, the time can be shown from edge to edge on the display for better readability and usability. For devices adopting XDR or Liquid Retina display technologies, a more crisp and clear font can be shown. FEATURES * Dark mode (night mode) is supported natively in app. The clock face can be viewed comfortably whenever it is in day time or in dark. * The clock can be displayed in either 12/24 time format. * Styling your own clock face with bold font, or to choose showing/hiding the seconds counter. * Timing and clock styling are made within the app. No network connection is required. For accurate time display, please make sure your phone’s clock is in-sync with the timezone that you’re in. * As no third-parties is involved within the process, all data are kept within the app. Made by PPES Developers & Contributors
