It WAS awesome.

I used this app for everything. It was so smooth. I used it for note taking in class, for annotating textbooks, you name it. And then there was the update corresponding with the new iPad release. It tried to be all cool and minimalistic but now it’s terribly laggy and pixelated. I am very disappointed. I’ve pretty much switched back to Notability at this point.
