All in one extension to manage your schedules. You can define multiple alarms, use the stopwatch with as many "lap"s as required or simply use the timer with pause and resume support.

This extension uses the built-in API to set alarms hence the extension works even if the UI is hidden or your browser gets restarted. This extension offers alarm sound snoozing which snoozes the alarm sound 3 times with 5-minute delay.

The extension displays a high-priority desktop notification when either an alarm or a timer is fired, also it plays two different sounds to get the user-attention.
