Can’t see your keys at night?
Use your pebbles backlight to illuminate your key hole and help you see.

HOW TO:
By pressing the up button the backlight will turn on and stay on permeant while the app is open (WARNING: the will drain the battery faster if left on)
Pressing down will turn the backlight off (after 3 seconds) and return it to normal watch settings.
Pressing the middle button activates the timer for 10 seconds then switches off the backlight.
