In the "Match" section, you will be presented with photos of users near you, and you will have the opportunity to express your preference based on the first impression given by the photo. You can choose to like by clicking on the heart icon or swiping the image to the right. Alternatively, you can click on the "x" icon or swipe the image to the left to prevent that profile from being shown to you in the future. If you want to immediately invite the user to chat, simply click on the messaging icon in the center.
