I've spent the last year developing this with my cofounder. Overall it's been an incredible experience that has consumed thousands of hours of our time and tens of thousands of dollars. We had a false start about 6 months ago but now we are finally ready to go live. I would appreciate it if any of you would take a moment to check it out and post your thoughts.
Throughout this process we have learned a tremendous amount about developing an app (from business plan to business scope and hiring developers), finalizing legal docs (ie acquiring trademarks, defending them, etc) screening graphic designers, trouble shooting and project management in general. I am happy to share our findings with anyone who has questions and interested in going down the path mobile entrepreneurship.
