You don't always want to buy things the moment you see them. Perhaps you may want to check it when you're around the store . Or maybe you want to wait on a price drop! This app would collect items you drop into the cart and bring up a 'spatial alarm' application on your phone! It doesn't require you to be on the app to get an alert . Its just like your normal alarm that runs in the background and well you can always let it snooze.
