Daddy Up is a free iPhone app designed specifically for dads-to-be. Whether you're a first-time dad or adding to your growing family, this app serves as a comprehensive field guide to pregnancy.

The app provides weekly information about your pregnant partner, affectionately referred to as "Lady Lumberjill." It offers rugged weekly baby-size comparisons, giving dads a unique perspective on their baby's growth. Additionally, Daddy Up includes trimester checklists to help dads stay organized and prepared throughout the pregnancy journey.

One of the standout features of Daddy Up is the hospital bag checklist, ensuring that dads have everything they need for the big day. The app also includes a journal log for dads to document their thoughts and experiences, as well as a contraction counter to help monitor labor progress.

Daddy Up goes beyond just practical features and also allows dads to create shareable baby announcements, making it easy to share the exciting news with family and friends. With wise words from seasoned dads who have been through this journey before, Daddy Up provides a handy tool for upcoming dads, offering more fun and less focus on the dainty details of pregnancy.
