What are your favorite iOS apps?

I've been on an app downloading spree and was wondering what some of your favorite apps are so that I can try them out. Here are some of mine:

  • Simple: I know, I know, this is a banking app, but it's the best damn banking app I've ever used!
  • Twitterific: easily the most well designed twitter client I've ever used. Clean and simple.
  • dots: I love this game. I usually don't keep games on my phone for more than a week, but this has a permanent place on my home screen.
  • Today: coolest weather app. I especially love the radar feature that let's you see exactly what you're under.
  • Task: I'm a structured person, so Task allows me to create quick and simple reminders and to-do lists.

So, what are some of your favorite applications? Any that stand out in design? Maybe UX? Let me know in the comments!
