asUMoveOn

This can be developed as a mobile app that displays you options to make a note of several things based on the current location as you move on.

As you pass by you might notice a shop with specific things that can be brought in future , or a hotel that you may plan to go later or something else that might interest you in future. You make a note of this into categories that the application provides.

Then ... when you need you can search for these from the data stored by your app.
