Downloading a Flashlight

Doing laundry, on a dim and misty day off from work.  Sipping ice-cold water, in-between.  During the second load, something blew a fuse.  Grumbling to myself, I searched around for a flashlight, so that I could find the right switch to flip.  I found a light ok -- but the battery was dead.  Pondering soggy laundry I wondered if my iPhone would cast enough of a glow.  Then I figured, why not try the app store?
