Excellent for tracking!

I am Canadian and this app is perfect for tracking USPS shipments to a drop off location just south of the border where I drive to pick them up. Updates are timely with little delay (as compared to eBay tracking). For me one of the greatest conveniences is the the app remembers your tracking numbers! I wish all the tracking apps did this - hint hint.
