Grindr (/ˈɡraɪndər/) is a geosocial networking mobile app geared towards gay and bisexual men, designed to help them meet other men in their area. 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 (the latter called Grindr Xtra). 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 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 precise 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. It is currently available in 192 countries.
The app is partially or entirely blocked in Turkey, Iran, Saudi Arabia, and Indonesia, and has been used by authorities in Egypt to track and arrest gay men
