I don't know about how you guys find anything when shopping in a large supermarket but I think there would be a great market for an app that when you enter a supermarket you could say Dish washer tablets and the phone would come back with say Aisle 16B lower shelf
Most of the items are bar coded these days so the codes could be got from the warehouse management systems and the relevant supermarket layout is obtained from the GPS when you enter the supermarket.
I've often wanted something like this - especially these days with more and more automated checkouts there are less "Humans" around to ask - and some supermarkets are really massive.
How about it some budding coders out there.
The phone might need to have some type of laser scanner to find / read the bar codes but just think of the amount of TIME this app would save users. !!!
Hands up those who have endlessly traipsed around a Supermarket trying to find even simple things. Pure purgatory - especially if one has kids in tow.
