Hot or Not is a dating platform and an app allowing users to select people by viewing and rating their photos.

HOTorNOT originally began as an online photo rating site. Users uploaded photos of themselves and the community rated the user photos on a scale of 1 to 10. The resulting average score was prominently displayed online to both the user and the public.

Over time, HOT or NOT extended into an online dating service, MeetMe. Similar to the functionality of the ratings service, users see photos of one another and click a "yes" or "no" button asking if one wants to meet the person.

Its new Facebook application now generates about a third of its logins.
