Very impressive app. Love the "It's cheaper than a Moleskin" tagline, haha. Once I get another iPad, I'll check it out. I use Evernote (which has a terrible UI), but I have so much data it's next to impossible to import it into any other system.
I'm currently in that crazy-making pixel-perfect OCD design polish phase that takes so long in iOS apps. If the design gods and the testing gods smile on me, it should be out before the end of the month.
