This app will allow you to help someone locate you, specifically in a dark area. For example, your kids are on stage, they look in the audience and can't find you. You are at a dark bar, or at a concert. This app will allow you to flash two colors at various speeds to attract someones attention and will also allow you to include some text as well, perfect for finding someone at an airport you are picking up. Give it a try, it's free!
