Apple users have been complaining about the iPhone’s Maps feature since it was launched Wednesday as part of Apple’s new operating system. The navigation app, which replaces Google Maps on the smartphone, just isn’t up to snuff, they say.

Problems ranging from mislabled plots of land to poor-quality business results have cropped up as users try out the program, among the features Apple added for the iOs 6 update.

Other new additions, such as Flyover — which shows users 3D models of select cities — and audio turn-by-turn navigation, have been overshadowed by the accuracy issues in Maps. Critics have noted that Apple has no public transit routes in the app, which can be crucial for users in big cities.

In response to the complaints, Apple spokeswoman Trudy Muller said that the program is a work in progress and that the company is listening to its customers’ concerns.

“We launched this new map service knowing that it is a major initiative, and we are just getting started with it,” Muller said. “We are continuously improving it, and as Maps is a Cloud-based solution, the more people use it, the better it will get.”
