Pinboard for Pinterest is a wonderful free iPad app. This is a real handy app that I'm glad I found out about, because since I've been using Pinterest I've been stuck to using my computer. Now w/ this app I can use Pinterest from the luxury of the iPad. The setup/install takes a bit to get used to (I hate copy/pasting on an iPad), but once it is installed it worked fine for me.
I highly recommend checking out Pinboard by clicking here!!
