Despite its zealous promotion of the Web and HTML5, Google still sees value in native mobile apps, which offer capabilities that aren't yet available or well-implemented in mobile browsers.
On Monday, Google released a native iPhone app for Google Latitude, its social friend-tracking service. Latitude for the iPhone allows users to continuously share location information with friends.
Keeping tabs on friends this way, however, has a downside: Google has warned that continuous location sharing transmits a lot of data, which could affect those with limited data plans.
Also, any kind of continuous data transmission taxes the phone's battery more than periodic or on-demand transmission. This was one of the reasons that prior to iOS 4 Apple disallowed background processes in third-party apps.
Google offers Latitude as a feature of Google Maps on Android, BlackBerry, Symbian, and Windows Mobile phones. The company previously released a Latitude Web app for the iPhone and desktop computer users.
The new native iPhone app represents an attempt to make use of the latest iOS capabilities. "Though we released Latitude as a Web application before the iPhone supported third party background applications, today’s Latitude app was built from the ground up using iOS 4’s new multitasking capability to support background updating," explained Google engineer Chris Lambert in a blog post.
Apple released iOS 4 in June and iOS 4.2 in November.
Google in the Enterprise SurveyThere's no doubt Google has made headway into businesses: Just 28 percent discourage or ban use of its productivity products, and 69 percent cite Google Apps' good or excellent mobility. But progress could still stall: 59 percent of nonusers distrust the security of Google's cloud. Its data privacy is an open question, and 37 percent worry about integration.
