advice needed please - my BF leaves his phone lying around and I occasionally scroll through his stuff - we know each other's passwords, I should add. He leaves pages 'open' and on a recently viewed page was a photo of a woman which had beneath it on the horizontal bar at the bottom (if it were on your photo roll, for example, it would have a trash can) there was a 'heart' symbol which presumably (if it were a hook up site) you might be able to click on the heart to show that you 'liked' someone........... is this a hook up site? Is anyone familiar with this app? Thought he was a trustworthy type....................
