Grindr is a location-based social application geared toward gay and bisexual men. Users create profiles in the app, and once active, Grindr uses their mobile phones' location reporting to provide each with a list of other users in the vicinity. Users can view each others' profiles and arrange in-person meetings.
Grindr is one of a number of geosocial apps for mobile phones. These applications use standard social and dating contact systems, but pair them with GPS or other location-based technology in order to provide users with matches that are in close proximity. A user can sort potential dates by distance, and even see approximately how many feet away a current match is from where he is standing. The application's slogan is "0 Feet Away," indicating its goal of getting potential matches into face-to-face meetings.
Grindr is available in both free and paid versions. The free version is ad-supported, and has some limitations on how many profiles can be viewed at one time. The Grindr Xtra service allows faster browsing of profiles, increased blocking privileges, and other features for a monthly fee.
Grindr faced some criticism in 2014 when an exploit was discovered that allowed anyone to scan the service and triangulate the location of its users. Since Grindr is available in countries where homosexuality is officially persecuted, this represented a potentially dangerous invasion of privacy. Grindr temporarily disabled the distance display feature, but reinstated it soon after when users complained.
