I had a rocketbook that I used for a while but scanning it in was always such a hassle. Plus I really like audio recording with my handwritten notes. I've switched to notability on an ipad with a paperlike screen protector and it's...okay.

I tried the livescribe pen, but the app is hot garbage and wouldn't record audio unless the app was in the foreground and the screen unlocked. Their support recommended I disable my lock screen and sleep timer. I sent the pen back to amazon for a refund.
