Foster’s 'Vordometer' by Adam & Eve

Created by Adam & Eve, users are encouraged to upload a photo of their girlfriend to their iPhone, which the app will then transform to show how they can be expected to age.

The idea comes off the back of a TV ad launched by Foster’s earlier this year, which sees the brand’s spokesmen Brad and Dan encourage a worried man to stick with his girlfriend as she may turn out to look like Carol Vorderman.
