The 3D baby models are why people download this. Rotate your baby in 3D, watch organs develop week by week, see how big they are compared to fruits and vegetables. It's the most visually impressive pregnancy tracker available. 80M+ downloads.
Weekly updates tell you what's developing this week, what to expect with your body, and what to ask at your next appointment. Daily content keeps it fresh. Size comparisons make it tangible - "your baby is the size of a papaya this week."

By Philips Avent - a brand parents already know from bottles and breast pumps. Free basic version with premium subscription for full access to all content and tools.
Compared to Flo ($49.99/yr), Pregnancy+ is more pregnancy-focused while Flo covers the full cycle-to-pregnancy-to-menopause spectrum. Flo has a larger community and more editorial content. Pregnancy+ has better 3D visualizations.
Compared to The Bump (free, 3D models, registry integration), both have 3D baby models but Pregnancy+ was first and the models are more detailed. The Bump adds registry features Pregnancy+ doesn't have.
Compared to What to Expect (free, editorial powerhouse), Pregnancy+ is more visual while What to Expect is more written-content-heavy. Different strengths for different learning styles.
If you want to SEE your baby developing in 3D, this is the app. If you want to READ about it, What to Expect. If you want to track everything in one app forever, Flo.
