This is a very poor app. It consumes tremendous amount of battery power because their server does not have adequate band width and my cell phone just shows the whirling dots while it tries desperately to stay connected. Their promise to give me a 15% off my first purchase coupon has not happened! They are not ready to do this, it should be called a beta app and then release it to the public in a year or two. I would love to offer more specific information to help their programmers, but there would have to be something that works in order for me to have constructive criticism.
