So what can Metro bring to the well-worn package-tracking schtick? Surprisingly, quite a bit. Feed Trackage a tracking number, and it’ll figure out which shipper has your bundle. You can assign your own name to the shipment. You can pin a tile on the Start screen that shows the current status of the delivery. Trackage syncs your entries, so you can look at them on multiple devices.
On the downside, Trackage still has trouble with international shipments.
