Online Stopwatch is an example of a free online program that allows users to access the full utility of a stopwatch, countdown timer or other form of digital clock. The stopwatch can be set and cleared using either the keyboard or its own digital interface which allows users to program in simple runs of numbers to set the length of a timed session.
Online Stopwatch uses Flash as its animating software, meaning it requires a visual environment in which to run. It can be programmed to operate in fullscreen mode, a useful feature when users want to block out all distractions and other programs.
The Online Stopwatch parent website has a number of utilities. It includes an interval timer and a talking clock so that the utility can be of use to the visually impaired and parties who have trouble reading digital displays. In addition, there is a metronome for use in music practice and other acoustic activities.
One of the basic functions of the site is a chess timer. This allows anyone with access to a phone or laptop to run a professional chess match by chess regulations. The timer can also be used to time sporting events such as split lap relays. As a final function, it includes a standard digital clock.
