M-Annotate (Mobile Annotate) allows users to annotate real-world landmarks with textual and graphical information. Just point your iphone at the landmark and you can choose to record your annotations or view any information annotated by others. Your annotation can also be automatically uploaded to Facebook via M-Notates Facebook integration.
The application aims to be a social-networking platform for users to share their knowledge, experience, and general information from personal photos, to tourist attractions and a wide range of businesses information.
