The sw is very good: stable, versatile and comprehensive. Couldt find (or think on) something better. Pros: - Intuitive interface. - No crashes. - Supports carriers I never even heard about. - The "push" feature ensures you have the status up to date - in dozens of shipments, only once the original carrier website had a more up to date information. - It "knows" its night already and you shouldnt the alerted while youre sleeping. Good! Even Apple took years to realize that. - The device synch feature was a nice surprise. Now I have both iPhone and iPad tracking all my shipments without double-entering the tracking info. Before that only my iPhone had the tracking set up. Cons: - Does not support Italian Post. (What I guess is not this manufacturers fault anyway) This was one of the best money I ever spent on iTunes Store.
