Stopwatch vs Timer - Understanding the Difference

Many people search for both stopwatch and timer, but they serve opposite purposes. A stopwatch timer online counts up from zero to measure how much time has elapsed — you use it when you want to know "how long did this take?" A timer, on the other hand, counts down from a set duration to zero and alerts you when time is up — you use it when you need to be notified "when will this be done?" AlarmOnline24 provides both tools: use this stopwatch online for measuring elapsed time with lap recording, and use our timer for time-limited activities that require alerts.
