About

Hey Peri

Features
Read full description

The weeks after a baby arrives are some of the hardest and least supported. Formal care mostly stops around six weeks, right when the fog sets in. Peri stays with you. Peri is a daily companion from pregnancy through the first few years of your child's life. It checks in, listens without judgment, and helps you notice how you are really doing, even on the quiet days when nothing feels wrong, and nothing feels right either. What Peri does: A daily check-in that meets you where you are. Talk as much or as little as you want. Gentle patterns over time. With your permission, Peri looks at sleep, activity, and energy from Apple Health so you can see how the weeks are trending, with no logging to keep up. A weekly reflection on how you are feeling, kept private to you. A simple summary you can share with your midwife, doctor, or doula at your next appointment. Peri is warm, never clinical, and never here to tell you how you should feel. Peri is a wellness companion. It does not provide medical advice, diagnosis, or treatment, and it is not a substitute for care from a qualified professional. If you are in crisis, call or text 988 in the US, or contact your local emergency services.
