A 45-year-old woman has revealed that she has given her husband permission to spy on her through her smartphone. Catharine Higginson told The Mirror that her tech-savvy husband James installed an app on phones belonging to her and their three children Daisy (19), Tilly (16) and Max (12), which allows him to track their location, see who they are with via the camera, download texts and listen in on conversations. She said that while she found the device intrusive at first, she had since come around to her husband's point of view and considers it a security measure. "James reckons it’s a safety device – and who am I to argue? I usually drive home through the countryside and now it’s winter it’s pitch black. My car keeps breaking down, so it has set his mind at rest that he is able to track me. "While I was very shocked at first about the extent of the snooping, I ultimately don’t have a problem with him doing this because I’m not up to anything." She went on to say she realises that, to others, it sounds like her husband is "being creepy and a stalker" but she remained adamant that he "wants to know we're all safe". "I can see it from my hubby’s point of view. Even so it did feel quite odd at first, in a Big Brother kind of way. And if any of us did actually go missing then the app would prove invaluable – in that case it’s an intrusion well worth it in my opinion," she explained. "As for spying on your other half? I reckon other couples are freaked out by the idea not because they’ve got anything to hide, but they’re thinking guilty thoughts – perhaps they regularly send flirty texts or are having an emotional affair. In short, they’d really rather like to have something to hide."
