Julie Black, Pinterest Product Manager, writing on Pinterest’s official weblog:

Now if you’re on your iPhone or iPad, you’ll see another kind of Pin: app Pins. Let’s say you’re Pinning workout inspiration to your Marathon Training board. If you see a fitness app that helps you reach your goals, you can download it right from Pinterest.

When you come across an app Pin, tap Install to download the app right to your iPhone or iPad without ever leaving Pinterest (you’ll only see app Pins when you’re using the Pinterest app on your iPhone or iPad).

Interesting collaboration between Apple and Pinterest. Although it’s only been a few days, I wonder how successful it will be given that every Pinterest user I’ve talked to hasn’t seen any app pins yet.
