30 Second Timer
Need a quick countdown? A 30-second timer is perfect for timed challenges like plank holds, wall sits, and speed drills. Use it for quick breathing exercises between sets at the gym, or to time a rapid-fire round in party games. It's also handy for brushing each quadrant of your teeth (dentists recommend 30 seconds per section) or timing short rest intervals during high-intensity training. This free online 30-second countdown starts instantly — just hit play, and an alarm sounds when time is up. Works offline, no ads, no distractions.
