Jorgensen, a user interface designer for a San Francisco-based startup, began using Apple Maps months ago, because Apple made it available early to people in its software development program. He said he finds himself relying on Google Maps running on his wife's Android phone instead.
User reaction on social media has been fierce. One Twitter user quipped that the lines of people queuing up to buy the iPhone 5 on Friday will be shorter, because the buyers will be misled by the new Maps.
The most-hyped feature of the new app is a "Flyby" mode that shows three-dimensional renderings of buildings and other features. It presents a convincing depiction of the canyons of Manhattan, but has a hard time rendering bridges and highway overpasses, which tend to look wobbly or partly collapsed.
The Apple app also has a tendency to judge landscape features by their names. For instance, it marks the hulking Madison Square Garden arena in New York as green park space because of the word "Garden" in its name. The TD Garden football stadium in Boston gets the same treatment.
Conversely, Apple Maps marks "Airfield Gardens," a farm and plant nursery in Dublin, Ireland, as an airfield. This prompted the country's Justice Minister, Alan Shatter, to warn pilots on Thursday not to land there.
Marcus Thielking, the co-founder of mapping-app developer Skobbler, said the lapses of the Apple app are surprising, particularly because Apple purchases map data from an established provider, Tele Atlas.
"We launched this new map service knowing it is a major initiative and we are just getting started," said Apple spokeswoman Trudy Muller. The app will work better the more people use it, she said, alluding to fact that users can report errors and omissions from within the app.
Google has been in the mapping game for much longer, giving it the benefit of years of error reports to help shape its maps.
There's been a Google Maps app on the iPhone since it was launched in 2007, but it's always come with the operating system. Now that it's gone from the list of "core" apps, users are finding that it's not available for download, either. Google says its goal is to make Maps available, but hasn't said when that will be.
In the meantime, iPhone and iPad owners can access maps.google.com through their browser, said Google spokesman Nate Tyler. The browser version has fewer features but uses a comprehensive mapping database, he said.
