'Tinder for threesomes' app Feeld helps match 'thrupples' looking for ...

A London duo are shaking up the dating world with their alternative app which helps couples find attractive singletons to have threesomes with.

Graphic designers Dimo Trifonov and Ana Kirova are the creators of the app Feeld, for individuals and partners looking to join or have a ménage à trois.
