Grindr is a geosocial networking and online dating application geared towards gay, bi, trans, and queer people. It runs on iOS and Android and is available for download from the Apple App Store and Google Play, Grindr comes in both free and subscription-based versions. The app makes use of a mobile device's geolocation, a feature of smart phones and other devices, 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 furthest 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 precise location.
