Set a countdown for any length of time and let the timer count down to zero for you. Enter minutes and seconds, press start, and watch the clock tick down. When time is up you get a clear on-screen message and a short beep so you do not miss it. This is the classic tool for cooking, studying in focused blocks, timing a workout interval, or keeping a meeting on schedule. You can pause and resume without losing your place, or reset to enter a new duration. It all runs in your browser with nothing to install, and because the audio alert is generated locally, the timer works even with the sound turned up in a quiet room. Your durations never leave your device.
