iOS: Sometimes the worst part about sipermarket shopping is organising your list in a way that makes sense for the store you're at. LocationList is an app that does that automatically for you, and the more you use it the better it gets.
LocationList is a very simple list app, but it learns as you use it. To start, you'll just enter in your shopping list and then head to the store. As you tick items off the list, LocationList remember that information and your location so it knows where those items are at in that particular store.
Eventually, that means that when you walk into a particular supermarket, LocationList knows how to order your list for the most efficient run through the store. It's free to check out and use with one location, but if you want to add multiple locations you'll need to make an in-app purchase.
