Duelle is a pregnancy tracking and education app built exclusively for women carrying twins, triplets, or more. Every piece of content, every tracking tool, and every week of your pregnancy is designed around the realities of a multiples pregnancy, including higher-risk monitoring, chorionicity differences, and the unique physical and emotional experience of carrying more than one baby.
What Duelle includes:
- Week-by-week education written specifically for multiples pregnancies, covering what is happening with your babies and your body from the first trimester through delivery. Free through Week 20. Full access through Week 35 requires a Duelle Premium subscription ($12.99/month).
- Content automatically adjusts based on your due date and chorionicity type, so monochorionic twin families see the content that is relevant to them.
- Growth and development tracking for both babies, with the ability to log appointments, scan results, and notes from your care team. Growth tracking requires a Duelle Premium subscription ($12.99/month).
- TTTS awareness content and early symptom education for families with monochorionic twins, delivered at the gestational weeks it matters most.
- A Care Team log to store provider contacts, appointment notes, and communication history in one place. Shareable care summaries make it easy to stay organized across your OB, MFM, and birth team.
- A built-in due date calculator and pregnancy timeline that accounts for the earlier typical delivery window for multiples.
- Medication tracking and appointment reminders require a Duelle Premium subscription ($12.99/month).
Duelle does not replace your medical team. All health-related content includes medical disclaimers, and the app is designed to help you show up to your appointments more informed, not to provide medical advice.
Duelle Premium: $12.99/month, auto-renewing. Subscription automatically renews unless canceled at least 24 hours before the end of the current billing period. Cancel anytime in your App Store account settings.
Who Duelle is for:
Duelle is for any woman pregnant with multiples who has searched for information and found content that was not written for her situation. It is for the woman who just found out she is having twins and does not know what to expect. It is for the monochorionic pregnancy that needs more specific information, and so many more.
Every heartbeat, accounted for.
