My app would be different, I am a GUI nut, so it would be beautiful, and functional, it would be free or at the most $0.99 (this is a learning experience for me, not a cash grab), it would be iPhone and iPad compatible, and it would on a daily basis scan and update tobacco blends. As for a BB/ Android version, BB would be more likely than droid, because the android marketplace is FUBAR and I'd want nothing to do with it.
