Tap a quick time or type hours, minutes and seconds. Press Start to begin and Pause to stop. The remaining time also appears in your browser tab title, so you can work in another tab and still see it. When the time ends you hear four short beeps.
A nap of 10 to 20 minutes can improve alertness without leaving you groggy. Longer naps can cause sleep inertia. Set the timer to 20 minutes and avoid napping after 3 pm so your night sleep stays on track. If you want to plan a longer rest in full sleep cycles, use the nap calculator.
