The app works pretty well. Some of the prices were inaccurate, but there is a space to update them for yourself and for others. It doesn't work a hundred percent but I'm sure they are working on it.
The real problem with this app is the design. It give suggestions on different stores you might want to visit to save money, and then tells you which items in your list you might need to find looks at different stores close to you, and produces combinations that will save you money. However, the store is it suggests might not carry the exact items you want. So the app says you might need to "swap out" items for comparable ones. comparable items for if that specific store doesn't carry it. However, it's almost impossible to tell which store they are telling the screen that gives you these options is designed very poorly. It's hard to tell which specific store does or doesn't have your items. It's also confusing when you switch back and forth from does and price comparison to your personal list.
Once they get the design kinks worked out, I'm sure this will be a very popular, very useful app
