Calorie Counting Website

I am looking to have a website developed that allows users to register for an account and manage their food intake and exercise. It’s basically used as a calorie counter website. Below are 3 of the sites that lead the market right now. I’m not trying to reinvent the wheel so I’d to take certain features from each of the sites. The main site that I like, due to it’s simplicity, is [[login to view URL]][1]. A couple of the other leaders are [[login to view URL]][2] & [[login to view URL]][3]. I’d like to look into having an iPhone & Blackberry app that allows users to log into their accounts and add food & exercise from their phones as well. The bottom line is that I want to duplicate the concept of [[login to view URL]][1] but with a different user interface. I’d like to make sure that I have space to allow for banner & AdWords advertising as they do on [[login to view URL]][1]. ## Deliverables I'm open to any suggestions related to this project so please feel free to offer any feedback.
