App shows you one user at a time. You can scroll through their pictures and Prompts, then choose whether to like or reject them by tapping the heart icon or 'X' icon.
Unlike other apps though, you don't have to like someone's entire profile. If they've got a specific picture or Prompt that piques your interest, you can like just that piece. It's a great way to let someone know that you're really paying attention to their profile, and not just hitting Like on everyone that comes your way.
When you like something, you'll also get the chance to add a comment. In other apps, you'd have to wait for a match to start chatting — here, you can start the conversation with just a like. Every like that you get will appear on your personal Likes You page.
