Hearts is an alternative to freemium dating apps. All features on the app are free. When a user is interested in matching with another user, they can send them a typed message. The recipient is notified about the message but the content is blurred. The recipient is free to view the profile of the sender. If the recipient opens the message then both the sender and the recipient pay for 1 match. The sender can also recall the message anytime before the recipient has opened the message.
