When you send a like to someone, you're letting them know you're interested. To like someone, simply tap the heart icon while viewing their profile in Suggested – this is always free.
For an even stronger signal of interest, you can send flowers using beans, our virtual currency. Flowers can be sent in Suggested or Discover and show that you really like someone. When you send flowers, your profile will instantly appear in their Likes You section with a virtual bouquet.
You can also like back people who have already liked you in Likes You. Non-subscribers can like back anyone they see unblurred, including those who sent them flowers. Subscribers can like back anyone, as all likes are unblurred for them.
