The initial purpose of this android app was to track my international packages, as I was begining to have a lot of them. I tried the other apps on the market but i didnt liked them because they were slow, or they asked a lot of info on the item in order to perfor the track, like origin county courier and end country courier, something that was ridicolous to me at that point in time. I was using the 17track site to track my packages, so I took a peek at their code and figured out what they were doing. I then started developing my own app based on their tracking api.
