Answering the questions is worth your time, because the more you answer, the higher your match score with other compatible users can be. As is only fitting for a swipe-based dating app, profiles are minimal, focusing mainly on profile pictures with a brief bio, but they do allow you to connect social accounts if desired, including your Instagram account, which can give people a better idea of what you're into via Facebook likes, and pictures of you visible on your Instagram. This is a simple feature that generates questions and quizzes to determine the compatibility of a user to another. Unfortunately, Tinder has a lot of straight girls saying that they're "interested" in women just to find friends or a threesome, and you'll still have men's profiles thrown into the mix when you didn't ask for that. According to their website, they have been rated among the top five mainstream dating websites in the world. This dating site has a strict anti-scam and spam policy to keep it secure and easy to use without any annoyances. Best for a date that's not a random hookup.
If nothing else, being accepted into something so "fancy" is a huge confidence boost.
It's almost impossible to find a dating site or app that doesn't have some sort of paid upgrade feature, but these are the sites where the free option gives you most everything you need to experience the full site paid options mostly give you more unlimited access, like unlimited swipes or returning to an accidental left-swipe, but to some people, that's helpful. Good luck! Overall, their hearts are in the right place, and I commend them for trying to promote the importance of safe sex.
