The first few months of parenthood can be an anxious time, but a new "all-in-one" baby app could help to make things a little easier.

Designed by US pediatric expert Dr. Jennifer Trachtenberg, known as "Dr. Jen," Baby Bundle is a one-stop shop for parents that acts as a growth and daily activity tracker and also offers parental advice, manages vaccinations and health check-ups, stores photos and provides baby monitoring services.

Parents can personalize the app based on their child's details and monitor daily activities including sleeping, feeding and diaper changing. Data can be compared to the statistical national averages and the app even suggests questions for parents to ask at their baby's next medical check-up.

There is also the option to get advice from other parents on the app's community forum, and create a photo journal to share with friends and family.

"As a mother, I know how precious time is. I wanted Baby Bundle to help parents stay organized so they can spend more time enjoying those precious but sometimes challenging first two years," said Dr. Jen, who, in addition to regular appearances on CNN and the "Today" show, has published two parenting books, "The Smart Parent's Guide to Getting Your Kids through Check Ups, Illnesses and Accidents" and "Good Kids, Bad Habits: The RealAge Guide to Raising Healthy Children."

Co-founder Nick von Christierson added: "In today's busy and tech-driven world, Baby Bundle helps new parents be the parents they want to be, rather than the parents they manage to be."

The app, available for download to iPhone and iPad in the US and Canada, is the latest in a line of multi-functional childcare tools, including White Noise Baby, which aims to lull newborns to sleep, and WebMD Baby, which offers videos, articles and expert tips.
