Grindr is a geosocial networking app geared towards gay and bisexual men, designed to help them meet other men in their area. It runs on iOS and Android, Grindr comes in both free and subscription-based versions. The app makes use of a mobile device's geolocation, which allows users to locate other users who are nearby. This is accomplished through a user interface that displays a grid of representative photos 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.
