Hearts?

Ive been using this app for about eight months. When I first got it it was perfectly fine, then they added the heart system. The bots are cool, so are the clubs, and they make the languages easy to learn. But the ads and the hearts!!! I havent used it in about a month for these reasons. If they took away the life system and the ads after EVERY LESSON, Id start using it more often.
