The launch of T-Mobile G1 included the rollouts of Ecorio and ShopSavvy, two applications expected be among of hundreds or more that might eventually populate Android Marketplace, Google's answer to Apple's App Store.
Ecorio's app takes advantage of the G1's "GPS in the background" to let users track their daily travels, plan the most efficient routes -- whether by walking or driving, for instance -- and record their own "carbon footprints" to see what kinds of personal impacts they are making on the environment.
On the other hand, a company known as "Big in Japan" -- the producers of the ShopSavvy app -- were drawn to the Android platform by the "flexibility" of the focal point on the G1's 3 megapixel camera, said Alexander Muse, the company's "Social Ninja."
The ShopSavvy app is designed to work with Google's search functionality to read bar codes on products such as boxes of software, and then conduct price comparisons among online sites and brick-and-mortar retail stores. For the retail outlets, ShopSavvy provides street locations, in addition to pinpointing the stores on Google Maps, said Muse.
