OpenTimer

Countdown Timer

A countdown timer app where you can start as many timers as you need. Add or remove timers using the buttons, and just touch the timer to start it.

When the timer is done OpenTimer will wake up your phone if it is unlocked, sound an alarm, and vibrate until you turn the alarm off.

Packages

Although APK downloads are available below to give you the choice, you should be aware that by installing that way you will not receive update notifications and it's a less secure way to download. We recommend that you install the F-Droid client and use that.
