Countdown Timer
Set a countdown with presets or custom time. Audio alert when time is up.
About Countdown Timer
Set a timer in seconds: pick one of the built-in presets or dial in your own duration, then let it run. When time's up, an audio alert fires so you don't have to watch the screen. Simple, but that's exactly the point.
It fits anywhere a clock isn't quite enough — resting between sets at the gym, keeping a presentation on track, timing a board game turn, or keeping pasta from turning to mush. Browse more tools like this one for quick, single-purpose utilities that stay out of your way. If you want a timed challenge with a bit more structure, Typing Speed Test puts a countdown to work in a different way.
Works best on any device with sound on; the alert is audio-only, so muting your device means you'll miss the cue.
