Alarm Clock

An alarm clock is a clock with an alarm often used to wake a person. Many clocks feature a variety of sounds and some use the radio as an alarm sound.

Buying Guide

There are many features available in today's alarm clocks. It's all about personal preference. For those who dislike sounding alarms, there are clocks available with a different form of stimulus. Some clocks use light, gently increasing sound and even smell. HealioHealth makes a Sunrise Stimulator Alarm Clock, which gradually brightens the room, simulating the dawn (see pricing section below.)

Clocks that escape may be preferable for heavy sleepers and frequent users of the snooze button. Clocky, made by Nanda, will run and hide if its snooze button is pressed. The next time it goes off, it will have to be found before it can get shut off (see pricing section below.)

There are plenty of other convinient features available including iPod docking, projection display, outdoor temperature, forecast, radio and sleep sound therapy.
