Most digital computers depend on an internal signal at constant frequency to synchronize processing; this is referred to as a clock signal. (A few research projects are developing CPUs based on asynchronous circuits.) Some equipment, including computers, also maintains time and date for use as required; this is referred to as time-of-day clock, and is distinct from the system clock signal, although possibly based on counting its cycles.

Similar to our #8 selection, this app uses a gradual brightness increase to slowly wake you out of your sleep, before laying down the hammer and buzzing to wake you up. If you’re waking up angry or abruptly (more on this in a moment), then this is the perfect trick to keep ahead. Just ensure your alarm clock also has a USB charging slot to keep your phone nearby. This works well if you position it differently than your gradual light alarm clock, as if you’re getting two sunrises instead of one.

Another type is essentially digital, and uses devices that use a code such as Braille to show the digits so that they can be felt with the fingertips.

The smaller and simpler the better when I’m traveling.”
