Grindr is a geosocial networking application geared towards gay and bisexual 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.
