And you need to reply to that message within 24 hours of receiving it, or the match also expires. Unlike Tinder, she only has one day to send you a message before the match expires. Using the app is the same as Tinder: swipe right or left on singles near you, and if a “connection” is formed by both users swiping right, messages can be exchanged. But that means when you get a message, you know she’s interested. Guys can’t send the first message - only women can reach out. Bumble is a great Tinder alternative, especially if you don’t mind women having to make the first move.
