The Timer tool for LightOS requires software version v430 or higher.
Creating a timer is simple, select the duration - either using the arrows to change the hours, minutes, or seconds, or by manually entering the duration by clicking the pencil icon in the top right. Press SET TIMER to activate and begin the countdown.
While a timer is active, you have the option to STOP or PAUSE the current timer. You can only set one timer at a time currently. Once the timer is complete you will have the option to dismiss the notification, repeat the same timer or enter a new duration.
If the timer or alarm tool are active, the alarm icon is visible in the top bar. From the home screen you can press that icon to jump to the active timer if there is one.
