Gifts HD is designed for multiple users in mind, each profile created has his or her own gift list and a password so no one can see gifts you are planning on purchasing.
Designed to look like a desktop with shopping lists and a calculator, Gifts HD’s interface provides the necessary info to keep track of your gift purchases, wrapping status and budget numbers.
I needed this mostly for keeping track of my gift ideas, but this app gave me lots of other things I didn't know I needed. Like keeping track of gifts needing to be wrapped and shipped, and tracking my budget.
Gifts HD is available for $4 from the App Store (20% of the App profits are donated to Toys-for-Tots)
