A Like shows another member that you’re interested in connecting.
An Incoming Like is a Like someone sends to you. You can see your Incoming Likes for free.
A Like Back is a Like you send to someone who has already Liked you. Sending Likes Back is free.
A First Like is a Like you send to someone who hasn’t already Liked you. An active Premium subscription lets you send up to 10 First Likes per day.
When you both Like each other, a Match may form. You can then message your Match for free, subject to account access and safety restrictions.
For example, if someone Likes you first, you can Like them back and message once you Match without buying Premium.
A Like or Match doesn’t oblige either person to reply or continue a conversation.
