Physicians Interactive’s free I’m Expecting pregnancy app touches 40 percent of all U.S. pregnancies, the company’s consumer division MedHelp has announced.

Available for iOS and Android devices, the application was used as a companion during nearly 1.6 million pregnancies in the U.S. last year – out of about 4 million annual births in the U.S.

I’m Expecting is focused on actionable insights that empower women and guide them toward a healthy pregnancy. Using the app, women can track and share a range of health data within the app, including their weight and pregnancy symptoms, and compare that data to health guidelines or other women in their same week of pregnancy to see what’s normal and what’s not. I’m Expecting also provides detailed tips on how to find symptom relief.

The application features daily pregnancy content, videos and other helpful resources, while providing access to MedHelp’s active pregnancy communities where thousands of pregnancy questions are answered every hour by other moms-to-be.

Using the I’m Expecting app, women can track and share a range of health data.“As one of the largest and most trusted online healthcare destinations, MedHelp’s goal is to offer mothers the most comprehensive support tools they need as they progress through their pregnancies,” said John de Souza, President of the Consumer Division of Physicians Interactive. “Our symptoms engine is a powerful example of that. For instance, I’m Expecting’s symptoms engine shows that 62% of women in week 13 experience nausea. This can be a very reassuring insight to a first-time mother.”

MedHelp is currently ranked as the sixth most visited health website by Hitwise, with 15 million monthly unique visitors to its dozens of communities, which focus on diabetes, heart disease, mental health and general health, in addition to its pregnancy communities.
