Looking For The Best PAID iPhone Apps That Relate To Business

I just got a great gift and I need to find some PAID iPhone apps that relate to business. (Thanks Honey!) I need to know which ones you guys can't live without and which ones to skip. I've gone through the free ones and downloaded the ones I know I love. The paid ones seem to be hit or miss so I need a little help.

So leave me a comment below on what your fav business related apps are. If it's Android, that is OK too as I have one of those as well. OH and if you have any fitness related ones ( other than c25K pro ) that you want to share, do tell!
