Been trying to track my wife's phone (Xperia Z) using google+ locations, but it sometimes does not update her location for hours; just this evening it was telling me she was at work 10 hours ago. Sometimes it's up to the minute, but 10 hours ago is useless.
(The tracking is needed for a health issue. Recently, she was out at night, lost, incapacitated, unable to use her phone.)
Can anyone recommend an app that does the job?
