Since the introduction of the iPhone Trucker app earlier this year, more trucking-related endeavors have entered the area where mobile communications technology and business intersect. The latest iPhone app is Trucker1, what developer 1st Guard Corporation is calling “the first mobile application developed specifically for owner-operators,” now available via the iTunes App Store. And, significantly, it’s free. 1st Guard is a leading provider of physical damage and non-trucking-use liability insurance to owner-operators and small fleets, and verified Trucker1 users will, as of January 1, 2010, receive “a 10 percent insurance discount,” the company said in a press release.
