Countdown Timer3.2.1

Sometimes you need multiple timers while cooking, working, or studying.
This countdown timer can be used with three timers at the same time.
You may also want to use multiple timers to prevent your children from playing too many games, one for the older child and one for the younger child.
This countdown timer is very easy to use, as the remaining time can be easily set with the three buttons.
It also has a notification function that notifies you with an alarm or vibration for a set number of times, even when your smartphone is in sleep mode.
* Never use this app for dangerous work (using fire, handling dangerous objects, etc.)
