Here is my latest creation, Halifax Explorer.
You can use it by going to: http://halifaxexplorer.ca
It is a tool to locate, or add, location based data. This can be anything including, but not limited to, trails, malls, shops, entertainment, places of interest, etc.
It was entered into an App contest and it is primarily used for the Halifax area (NS) but it technically would work anywheres.
The only data it has right now IS for Halifax, but try it out and tell me what you think :)
Forgot to mention, I am working on an update to include a few enhancements such as setting location by click, and adding images.
