Helpful Flashlight App for Travelers

Via AARP, a must-need travel app:

You’re in a dark restaurant and you can’t read the menu. Or, you’re in a dark hotel room and need to find the bathroom in the middle of the night. Download a free flashlight application. I don’t know why this isn’t a standard feature on the smartphones. But, thankfully, there are scads of flashlight apps for you to download.
