Grindr is a geosocial networking application geared towards gay, bisexual, and bi-curious men. It runs on iOS and Android. Available for download from the Apple App Store and Google Play, Grindr comes in both free and subscription-based versions (Grindr Xtra). The app makes use of the device’s geolocation, which allows users to locate other men within close proximity. This is accomplished through a user interface that displays a grid of representative pictures of men, arranged from nearest to farthest away. Tapping on a picture will display a brief profile for that user, as well as the option to chat, send pictures, and share one’s location. Grindr was the first gay geosocial app to launch in the iTunes App Store and has since become the largest and most popular gay mobile app community in the world currently available in 192 countries.
