STANDARD.CO.UK - Jan 18 - The app, which is just eight weeks old, invites users to leave reviews of people they've dated (including a star rating). If they've got a big date coming up, they can search the app's database to see if the person has already been reviewed or, if they've just been on a date, they can create an account for the person. Users can only create an account if they have the person's phone number: at which point the date receives a text message, asking them to verify their account or request to have it removed. The reviews are anonymous.
