I wouldn't object to an App, but as jfmorris states, it's pretty good across mobile devices (at least for me on iPad and iPhone). When I'm using the site on those devices, I don't have to re-login every time. My Windows computer is another story, requesting me to login each day. I run several spyware cleaning programs as well as deleting browser cookies, each night, which is probably deleting my login credentials. I don't do this for my mobile devices, which is probably why I'm always logged in. If they create an App and also leave what they currently have in place, it would be a users choice to install the app or not, thus leaving the current format available for those that don't.
