I want well designed apps! Help!

I love using apps like Today, dots, Twitterific, Simple, Agenda, and Rdio. Well designed apps that I can just browse through menus and the sort just to see what they've made. I'd really like to know what apps you guys use that are in the top of their class. And no, don't give me stock applications, I'm writing this to discover new, beautifully designed applications. Sound off in the comments!
