Features
Read full description

Elceedee is a stylish, retro-inspired LCD clock that brings time to life with bold, vibrant displays. A giant central clock, with the corners yours to fill: the date, live local weather, or the time in up to four cities with your own labels. Swipe between four styles, each customizable in any color, with adjustable brightness and a real LCD effect. Time, date and temperature follow your phone's settings, or set your own: 12- or 24-hour, Celsius or Fahrenheit. Auto-layout fits the clock to any screen, in portrait, landscape, on iPad and in split screen, and the screen stays on while Elceedee is open, so it makes a great bedside clock or sits perfectly on your desk. Weather uses your own free OpenWeatherMap API key. No ads, no in-app purchases, no nonsense!
