Good app; I like it a lot. Unlike others, I havent experienced any glitches, thankfully. (But Im not syncing between two devices either, which is where most of the issues seem to be stemming from.)
One missing feature prevents the app from getting 5 stars from this reviewer: theres no way to add a personal note to a quote. I often want to explain the meaning of a quote, explain how I came across it, or make some other such comment. This missing feature is important enough to me that Im beginning to think of storing my quotes in some other fashion. (Another quote app? Within Evernote?) Developers: PLEASE add an optional Notes field!
