Why you want it: This intuitive app lets you quickly and easily create lists for multiple stores using text, barcodes or your voice. It also keeps track of frequently purchased items so you can make sure they are always included each time you create a shopping list. Notice that you’re running low on milk? Simply scan the barcode of the item in your fridge, and Grocery IQ will automatically add it to your shopping list. And unlike other list-making apps, this one lets you enter in the quantity, package size and unit price of each item. This handy app will even let you add your loyalty cards. Let’s be honest - are you really going to miss all those scraps of paper with half-written lists on them drowning in your purse? We didn’t think so.
