The upside is that your matches won’t languish, forgotten, as it puts a bit of pressure on you to communicate in a timely manner. Likewise, men can also choose to extend the time limit for 24 hours if they’re really hoping to hear from a particular woman. The downside is that if you’re super busy or a bit forgetful, you might miss out on the opportunity to make your move, although you can extend this window by 24 hours if you’re really keen to chat but haven’t had time. Once you’ve made a mutual match with somebody of the opposite gender, you have 24 hours to make the first move, and the man gets 24 hours to respond.
It also means you won’t waste time filtering through unwanted messages in your inbox. You have total control over who you start up a conversation with, which means no creepy unsolicited messages or pictures. On Bumble, women are in charge - a ballsy move.
