The Light Phone II has an alarm tool included in the menu out of the box. It's a very simple alarm.
Setting Alarm:
If there is not a currently set alarm, the alarm tool opens directly to a keypad so you can quickly set an alarm. Enter the correct time, then press the alarm icon to set an alarm.
Once an alarm is set, you'll see it confirmed. You can now delete that alarm by pressing the "X" to the left of the set alarm. You can also add multiple alarms using the "+" icon at the bottom.
Alarm Details - Repeat Daily:
You can click into any alarm that is set to bring up that alarm's details. There is a toggle for making this alarm repeat daily. A repeat icon is displayed next to that alarm, indicating it will repeat daily.
Alarm Volume:
While inside the alarm tool, using the volume UP or DOWN buttons will control the alarm volume.
Alarm Sound:
Preview and select your alarm sound in the settings:
Open Settings > Notifications > Select Alarms and pick your sound option
Alarm Sound Options:
Off: when it's time for the alarm to alert you, there will only be a visible screen change, no vibration or sound.
Vibrate Only: the alarm will vibrate but will not make any sound
Various Sound Options: click on a name to preview its sound
How to Remove the Alarm from your Phone's Toolbox:
