It's called Aisle Mapper, and we took it to the Pathmark in Cherry Hill, N.J. to put it to the test.
"Aisle Mapper was born out of many wasted hours walking the supermarket," said the app's inventor, Chad McGroarty of Cherry Hill.
McGroarty says he created the app to help fellow aimless shoppers find their way in the food aisles. It uses a GPS tracking device.
"It will pinpoint where we are standing and what store we are standing in," he told Action News.
Then all you do is make a list by checking off what you need from a thousand different items in the database
Aisle Mapper lets you know which items have already been located.
If the items aren't already on the map, you can add the location for your own future use, and for other shoppers.
You get in and out in half the time. And McGroarty says it can also save you money
"The longer you are in the store the more you are going to buy," he said.
And you get something in return for for helping map the items that aren't already in the system. McGroarty has created a badge system where you can win prizes and coupons.
Aisle Mapper is available for the iPhone, iPad and iPod Touch.
