Birth is one of the biggest moments of your life. Most people go into it underprepared, not because they didn't try, but because the information they actually needed was never in one place. Flo to Grow is birth and postpartum preparation built by an accredited doula — someone trained to support you through birth and the weeks after. It's the kind of guidance, the questions to ask, and the calm perspective a doula brings, in your pocket, week by week. PREPARE FOR YOUR BIRTH A birth plan is a form. This is something different. Reflect on your values and how you make decisions under pressure, then translate that into discussion points to share with your care team. Not a plan to hand over, a conversation to keep having. Learn BRAIN, the framework for slowing down any decision in the room. PREPARE FOR WHAT COMES AFTER The fourth trimester from day one. Feeding without judgment, sleep, recovery, your first 24 hours, and matrescence, the identity shift nobody warns you about. FOR YOUR SUPPORT PERSON Week-aware guidance for partners. How to show up well, in the room, in the conversations before it, and in the early weeks. Always free. FOR DOULAS AND MIDWIVES A professional workspace that sits alongside your practice. Manage your client list, see what each client is working through, and access decision-support tools for the room. No ads. No noise. Just what matters.

About

FourthTri

Features
Read full description

The weeks after birth are about you too. FourthTri is a private, informational companion for your own postpartum recovery: your healing, your mood, and your own feeding notes, with red-flag reminders always close and a clear summary ready for your six-week visit. What FourthTri does: - A healing log for bleeding, pain on a 0 to 10 scale, and incision or perineal comfort, with your recovery day and week always in view. - A gentle mood check-in: one tap for your sense of the day plus a short self-authored reflection. It is supportive and informational, never a screening test or a score. - Red-flag reminders, always free: the signs that mean you should reach out, each with plain-language seek-care guidance and emergency routing. - The Six-Week Visit Summary: a clear, free PDF of what you logged and what is worth raising, ready to share with your provider. - The full 12-week recovery timeline with Pro: your healing against typical postpartum bands, with your mood trend overlaid. - A maternal feeding and pumping log with Pro that is about you, not the baby: latch pain, engorgement, nipple healing, supply, and your own pump output. FourthTri does not track baby intake, diapers, or baby sleep. - An Apple Watch app for a one-tap mood and quick logging from your wrist, a watch-face complication, and a Home and Lock Screen widget with your recovery day and phase. - One gentle daily reminder to check in, if you want it. Never pushy. - A gentler-wording option, with less focus on the baby, for anyone whose recovery is tender. - Private by design: your log lives on your device and in your personal iCloud, synced across your devices, with an optional Face ID lock. No accounts, no analytics, no tracking. Free and Pro: - Free: the healing log, the mood check-in, every red-flag reminder, and the Six-Week Visit Summary. Safety is never paywalled. - Pro (Lifetime): the full 12-week recovery timeline, the maternal feeding and pumping log, trend analytics, and your complete history. One payment, yours forever, no subscription. Important: FourthTri is an informational companion. It is not medical care, not a diagnosis, and not a substitute for your provider. Its ranges and reflections show what you logged, framed by reputable on-screen cited sources (ACOG, Postpartum Support International, NHS), and when something looks worth mentioning it reminds you to talk with your provider. In an emergency, always call your local emergency number.
