Slice is a nifty little app that keeps track of your online purchases for you. It tracks the shipping (if available), even letting you know when something has been delivered to your door (which is invaluable if you are at work, trying to decide to swing home before that meeting to see if there’s a package waiting for you!). It also keeps track of your online spending, which is great if you are trying to track where your money goes for budgeting purposes.
How does it work? It is alerted anytime you get a confirmation email from an online purchase, and gathers all of the pertinent information for you. It even works with itunes and netflix purchases.
