The 'Stack' is one of the unique features of FlickStackr/PhotoStackr. It is a quick way to mark photos as favorites and have them in a single place for later viewing.

How can the Stack be useful for you?

Here are some examples on how you can use the Stack:

• Save a photo as a 'local' favorite.
• Save a photo for further review. Maybe you're looking for photos with a specific subject, want to mark them, and later review them to choose the best one.
• Have your Sales Catalog photos available for offline viewing.

Tip: The stack is per device and account. Each account has his own stack. The stack can be shared across devices only if you enable the iCloud functionality in FlickStackr/PhotoStackr.
