I need an iPhone/iPad/Android app. I would like it designed and built. It is a fairly simple idea for a niche market. Users would be able to drop pins and leave comments for others to find and utilize and leave their own comments, maybe even a tips and training area with links to outside sources. I would like the app free to use with ads generating revenue. I would like to discuss using a percentage of that revenue to maintain the app. Looking for Colorado based people to start with the Denver area, though eventually hope to draw users from around the world to drop pins in their local areas.
