It is available on iOS and Android devices in both free and premium versions (the latter called Grindr XTRA and Grindr Unlimited). It was one of the first geosocial apps for gay men when it launched in March 2009 and has since become the largest and most popular gay mobile app in the world. Grindr is a location-based social networking and online dating application for gay, bi, trans, and queer people, and men who have sex with men.
