Apple's Find My Friends app is designed to make it easier for friends to meet up, showing a live location on screen via GPS which your friends can watch。
The idea is to make it easier to find friends on a night out, or ensure that people don't get lost on holiday。
But one wronged New York husband claims that the app - which uses GPS to let designated friends 'see' where you are - has revealed that his wife was lying to him。
He did, however, have to activate the app on her phone without her knowlege first. The service is 'opt in', so friends have to agree to 'watch' one another。
The unnamed New Yorker, who posted on Mac forums, said, 'I got my wife a new 4s and loaded up Find My Friends without her knowing. She told me she was at her friends house in the east village.'
'I've had suspicions about her meeting this guy who live uptown. Lo and behold, Find my Friends has her right there.'
He claimed that the app showed that she was in Manhattan, not where she claimed she was。
'I just texted her asking where she was and the dumb b***h said she was on 10th Street.'
'Thank you Apple, thank you App Store, thank you all. These beautiful treasure trove of screen shots going to play well when I meet her at the lawyer's office in a few weeks.'
The technology isn't new, either. Users of previous versions of Apple software could have used the Find My iPhone software in much the same way, if they had someone's MobileMe password。
Google's Latitude service offers a similar opt-in user-tracking service also. But so far, Latitude lacks the mainstream appeal of Apple products, and remains a niche technology
