Improve web experience on mobile devices
I use papaly app in iPhone and it is great. But, when I want to share my bookmarks with friends sharing an URL, they are directed to your web site that is not ready to mobile browsers. You should invest in a layout for mobilie browsers and, once there, make web site suggest the download of your app in the phone. Even better if, once the user has app installed, the shared URL should be opened direcly into it.
