A count up timer is a device that is able to measure time in increments of seconds, minutes, hours, etc. The purpose of this type of timer is to allow the user to see how long an event has been going on without having to refer back to their timeline. This type of timer has countless benefits for both personal and professional use.
In other words, a count up timer is a device that counts up from zero upwards. This provides an individual with a better representation of how much time has elapsed when they are setting a timer.
Many people who are preparing for an exam or quiz use the count up timer to help keep track of how much time is left. Another use of the count up timer is for cooking, as it is more convenient than having to glance at a clock or watch that may be difficult to read. The timer can also be used if someone needs to take timed medication on a regular basis.
