A Danish zoo has developed a 'Tinder' for orangutans in order to track mating preferences.

They have shown a female orangutan potential mates on an iPad to see if she will choose one in order to improve her mating chances.

If she seems to prefer one over another, they will choose that mate to come over from an international zoo, which could be as far away as Singapore.

The four-year experiment is called "Tinder for orangutans" and the Apenheul primate park in Apeldoorn will let 11-year-old Samboja look at potential partners from an international breeding scheme.
