So what would you do if your OH had downloaded this app (its a messaging app which on the surface 'could' be innocent, a bit like snapchat) but he'd previously admitted to using it to chat 'innocently' to random women. He'd since deleted it (as you went mad because he'd downloaded it in conjuntion with with a swingers app which isn't quite so innocent) but you see today, has now reinstalled it on his work phone.
