What is your favorite weekly planner iPhone app?

Asked by bezdomnaya (1440) November 22nd, 2009 from iPhone

I just got a new iPhone, and while I’ve downloaded numerous apps for games, news, fluther, etc., I have yet to find a good planner app.

I need it to have a weekly view with at least 8am to 11pm daily. I would also like it to be streamlined (not uber fancy, just want to be able to see my day and week mapped out). Do you have one that you like to use? If so, clue me in, please!
