The Light Phone II has an alarm tool included in the menu out of the box. It's a very simple 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.
While inside the alarm tool, using the volume UP or DOWN buttons will control the alarm volume.
