I have:
-WebMD Pregnancy- gives you updates each week on what your baby's development is, what body changes you may experience, a journal for entering info or thoughts, info on nutrition/exercise/etc, and knowledge quizzes to brush up on your baby brain.
-babycenter My Pregnancy - has a different layout than the WebMD app and has other useful info and Q&A articles.

For health/exercise apps, I have SculptMyPregnancy, which has exercises (with videos for each) for each month and tracking options, etc, and also the March of Dimes My9Months guide, just for an extra source of information. It's set up sort of like a linkable, surf-able e-magazine.

I use Babybump & have liked it well enough (keep daily notes, weight, appts, search baby names, make a birth plan, etc). I like the community set up too.

It's a free app with the option of a paid for extras like the contraction counter & changing your background (there may be others too but I can't remember from when I upgraded). I'm now using it through a second pregnancy! =)

I have I'm Expecting (my favorite), What to Expect, and Baby Center's Pregnancy. Love them all.

@LatteLove: I have a ton of pregnancy apps and must say that Sprout is one of my least favorite, but you should download it (it's free! and you get access for the first few days to the paid version, which then reverts to the more basic free version if you don't upgrade) and see what you think. Everyone has different styles and amounts of information they like/features they want. So far I like the What to Expect and Health & Parenting Pregnancy apps--both free as well.
