Track your shipments directly from your iPhone or iPod Touch.
TrackIt EN is a simple app for tracking shipments from various carriers like FedEx, UPS, DHL and more. Simply select your carrier, type the tracking number in and press the button. It’ll load up the carrier’s tracking website with all the information you would get on your home computer.
Two problems I had with this app is that there was no back button after you tracked a package. You’ll have to exit and reload the app. And there is no option to save tracking numbers so I hope you’ve got a good memory.
