See how much time is left at a glance. Color Timer is a visual timer with a full screen countdown. As time passes, the colored area shrinks, giving you a clear sense of the time remaining. Set it on your desk for a study session, glance over while cooking, or keep your next presentation on time. A clear screen for your countdown Large numbers and vivid color fill the timer screen. There are no ads on the countdown screen and no full screen ads to wait through before starting. Keep the timer open and your screen stays awake while the countdown runs. Save it once. Start with one tap. Save your favorite timers with a name, duration and color, then start them directly from the home screen. Choose 1, 5, 10 or 25 minutes with quick duration buttons, reuse a recent duration, or set your own hours, minutes and seconds. Big numbers, in portrait or landscape Use your phone or tablet upright on your desk or sideways for a meeting, presentation or class. Choose from 18 color themes. Turn on the finishing-soon cue for a change in color and an on-screen message as time runs low. Pause, adjust and keep going Pause and resume, add a minute, or restart when you need to.
