Old alarms and timers rarely eat storage, but they pile up as visual noise that makes your daily alarm hard to find.
Short answer: delete alarms one at a time if there are only a few, or clear the Clock app's storage to wipe every alarm, timer, and stopwatch setting at once.
Why the Clock app feels cluttered
Most native Android Clock apps, including Google Clock and Samsung Clock, do not expose a "select all" or bulk-delete option for alarms. After a couple of years of one-off flight, meeting, and nap alarms, you end up with dozens of disabled entries crowding the list.
The clutter is organizational, not storage-heavy. Each alarm is kilobytes of metadata, so the cost is visual clarity, not gigabytes.
Deleting a few alarms manually
If the list is short, the manual path is fine:
- open the Clock app
- tap the Alarm tab
- expand an alarm by tapping it or the dropdown arrow
- tap Delete
Repeat for each alarm you no longer need.
The fast way to wipe everything
If you have dozens of alarms and timers, clear the Clock app's storage instead:
- open Settings
- go to Apps and select See all apps
- open Clock
- tap Storage & cache
- tap Clear storage and confirm
The Clock app opens empty afterwards, so you will need to recreate your daily alarm and any saved timers from scratch.
