Set a Timer in the Clock App auf Xiaomi
The Timer function in the Clock app runs independently from alarms and reminders. It counts down a fixed duration and sends a notification once that duration ends, which makes it the right tool for tasks with a clear deadline, like placing a last-second bid on eBay or checking on food in the oven.
Open the Clock app and use Tap on Clock to reach the tab overview, then switch to Tap on Timer. Enter the hours, minutes and seconds you need, confirm with Set the Timer and tap Tap on Start to begin the countdown.
Once running, you can pause the countdown at any point with Tap on Pause, which freezes the remaining time until you resume it. To end the countdown early or start over, use Tap on Stop / Reset, which clears the timer completely.
Unlike an alarm, the timer does not repeat and disappears from the screen once it fires, so it will not clutter your alarm list. If you need a recurring daily reminder instead of a one-time countdown, an alarm is the better choice.
