How does Grindr work?The app uses a grid format to display profiles. Grindr is a location-based service, so profiles show up on the grid in order of proximity to your exact location. Every profile is shaped by each individual, so share as much or as little as you’d like. Display up to five images total (with no full nudity allowed), create a bio, express what it is you’re looking for and what you’re into, give your height, weight, and more. Alternatively, you can choose to have a fully blank profile that reveals zero information to stay discreet.
