Call Notes is an Android app that lets you pull up annotations you've made in your contacts while you're on a call. Because what good are those digital flashcards if you can't see them when you actually need them?
So if you're on a phone interview, you won't forget to ask your potential new employer about his two kids. Or when you're chatting with a girl you've been out with once, you can remember that she's from Melbourne. And you can add new notes while you're chatting, so you retain new personal tidbits.
