Best of both worlds please

Dear Duolingo, why cant we have the best of both worlds?
I love the bots, layout, and new percent tracker in this version, and the master skill is nice too.

BUT why did you bring back the hearts?! I liked it better when the progress bar set itself back a bit when you got something wrong.

Also why cant we have the best of both worlds iOS and android. I love the android achievements. And you can actually pay to remove ads in android. But I wish by paying you received something more than just no ads.

Anyways, Duolingo is one of my favorite apps, but this update is a little annoying, yet visually pleasing.
