10 Minute Timer

A 10-minute countdown timer set and ready to go: the display already shows 10:00, so all you do is press Start. When the 10 minutes are up it flashes and sounds an alarm.

Need a slightly different time? Use the +1:00 or +5:00 buttons to extend it, or pick another preset below. Prefer a fully custom time? The main timer lets you set exact hours, minutes, and seconds.

How it works: press Start to begin the countdown, Pause to hold it, and Reset to return to the set time. The +1:00 and +5:00 buttons add time on the fly. When it reaches zero the display flashes and an alarm beeps until you press Stop — turn the alarm off with the checkbox if you want a silent timer. The tab title shows the time remaining so you can watch it from another tab.
