I use it a lot an don't find it too buggy - but the interface is awful on iOS. They took a decent, simple interface (table view) screwed it up into some new skuomorphic design and then in iOS 7 took that and made it even worse.
Here's a side by side of iOS 6 + 7. They are both terrible imho[1]. The Android app is much more simply designed and much nicer to use[2].
Before my eyes can locate the note's content -- the reason I'm looking at the app in the first place -- my brain has to notice and dismiss all of the unchanging but visually dominant UI elements grabbing for my attention.
In iOS6 screenshot, the only information is "3570 Notes". We can assume that Tom Negrino didn't need a prompt to remember his own name.
At least the screenshot of iOS7 version has a few snippets of user content. But, was the decision to make everything green made by someone who uses the product heavily? I doubt it.
