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.

The clearest difference is in-app purchases: BrightOak at none against FourthTri's 1. BrightOak also leads on iOS requirement (15.1 vs 18.0). On price, ads and device support there is nothing between them.
