Is it really Apple's font? I believe WhatsApp on Android uses the same. I guess everyone identifies them as Apple's because WhatsApp is not popular in US. I find it way uglier than Google's, too much detail makes them unusable at small sizes.

Anyway I find emoji worsen the communication. There was a time where I could just use :) when I was smiling and :D when really laughing. Now there's so much different smiling variants that you have to use at least 3 laughing-with-tears to convey even a little amount of joy so the other side doesn't think you're just dismissing them with a normal non-laughing smile.

PS what's going on with scrolling in the second link?
