I'm looking for a package tracking app that will sync with a web application for use on a PC. Right now, I use a great desktop package tracking site, TrackthePack.com, but they refuse to build an Android app. I would prefer an app that I can use both on the desktop and have the same stuff show up on the Android app. For one thing, it's a lot easier to enter the tracking numbers on the desktop than on the Android. Anybody know of one that does this?
