Sure, it seems like a great idea to hop on Tinder at 4am after you've been at a bar. Except no one will be there to get your eggplant emoji. Also, stop sending eggplant emoji.
But if you're looking to actually make a connection with someone on OKCupid or Tinder, you ideally want to be looking at a time when the most potential mates are online. Well, Nielsen, a global information and measurement company, studied the trends of OKCupid and Tinder users and discovered the magic hour. And that hour is.... 9pm. That's actually pretty early for a booty call.
If you log on anytime between 8pm - 10pm you're golden. Traffic trends down on both sites after that, and the wee hours of the morning actually see the least amount of users. Obviously, don't log on then, unless you like chatting with yourself. But why do you need a dating app for that?
