Startup Idea : ourguide connecting people with places

An audio guide you can make, share, follow others, include audio, map locations, text, video and pictures.For tourism, art projects, education, exercise, estate agency, guide, plan and exchange experiences in a space.The app will allow you to create an audio guide in your city, where you can record a step by step guide with instructions and or information. It should be possible to save a tour so to follow offline.I imagine it like youtube where it is across between social media and public media.
