This app is about to cause an unnecessary divorce

My son-in-law thinks my daughter is cheating on him because this app is such a screwup. I even paid for this app and I usually dont pay for apps. Is there a way to be refunded? I live with them so I know for a fact my daughters comings and goings. This app has ruined our holidays.
