Google is introducing an application that will connect Android smartwatches with Apple's iPhone, escalating the rivals' battle to strap their technology on people's wrists. The move thrusts Google on to Apple's turf in an attempt to boost the lackluster sales of watches running on its Android Wear software. The program uniting the devices running on different operating systems is being released Monday in Apple's app store. Until now, Android watches only worked with smartphones powered by Android software, just as the Apple Watch is designed to be tethered exclusively to the iPhone. Google's new app, though, will enable the latest Android watches to link with the iPhone so people can quickly glance at their wrists for directions, fitness information and notifications about events, emails and Facebook updates.
