The smartest trip planner I have seen.

This is how all trip planners should work. A little rough around the edges but really good way to plan a trip
This app allows you to organize your trip with itinerary. Just set your trip dates, select items from list of Museums, Attractions etc. add them to your itinerary by time of day and then shows you a map of your items only in the order that makes sense. It allows you to group your destinations by proximity.
My only issue with these apps is the lists are missing really major items. It doesn’t seem that hard to me to list ALL the museums in Manhattan. And is it too hard to list destinations in alphabetical order.
Don’t ever expect that an app like this is going to be a source for restaurants or reviews on anything. Do your homework on Google. Enter your choices in the app.
