While you can meet people for casual dates or casual sex on any of these apps, Tinder reigns supreme in this category. The app is extremely straightforward to use, though that does mean people make quicker snap judgments, which can devolve into focusing more on someone's photos instead of their bio and interests. To match the pace, try to pay attention to your pictures and how they can best represent your dynamic personality and what you're all about. What do you think?
