Hi everybody! Can any one help with something I'm looking for?

I want a database type thing that can sync/run between my mac and Iphone and I can log stuff around my house. I mainly want it to log my DVD collection. But the more options the better:-)

In addition

I'm looking for a an app that again can run between my MacBookPro and Iphone4 and allows me to keep track of my finances etc

All help is greatly appreciated and welcome!
