I tend to only download apps that are recommended to me, since random downloads have never worked out so great. For instance, the one I use now for task management is called Wunderlist. Google them and see how much effort they put into their marketing and brand. It works! I'd suggest using them as a template for how to arrange your marketing / user adoption and go from there. Best of luck!
