Makes you manually choose courier. Other apps detect the courier automatically based on the tracking number.
Also, doesnt automatically paste the copied tracking number from the clip board like other tracking apps do.
Tracking #s that get delivered automatically get archived into a delivered folder that can leave you looking for them.
Nice link to website of shippers.
Good points include icons of what shipper performed what portion of the shipment.
