The Belly Button is a simple, single-purpose tool for the one moment that needs one — the moment labor begins. When it's time, Mom taps the screen. A sheer curtain slides up, the belly is revealed, and one tap on the button sends a clear, instant alert to her whole circle: care team first, then close family, then everyone else — in the exact order she chose, with the exact timing she chose. WHO IT'S FOR • Moms-to-be who don't want to dig through a contact list while in labor • Care providers (OBGYNs, midwives, doulas) who need to know first, every time • Family and friends who want to be in the loop without pestering Mom HOW IT WORKS Set up your notification groups before labor begins. Pick who hears first — usually your care team — and how each contact prefers to be reached: push notification, SMS, or email. When labor starts, one tap dispatches them all in the order and pacing you set. Recipients confirm receipt with a single tap, so Mom always knows the message landed. GENTLE ON THE INSIDE, RELENTLESS WHEN IT COUNTS The Belly Button sends time-sensitive alerts with a distinct sound, built to break through Focus and Do Not Disturb so your care team sees them right away. Labor doesn't wait. BEYOND THE BIG DAY Send milestone broadcasts as your story unfolds — contractions starting, on the way to the hospital, baby is here. Add a real photo of your newborn when you're ready to share. The whole circle, all the way through. WHAT'S FREE AND WHAT'S PAID The Belly Button is free to download, and everyone you invite (your care team, family, and friends) joins and receives your alerts for free, always. To set up your circle and send labor alerts as the mom, a one-time purchase of $9.99 unlocks 12 months of access. It is a single charge, not a subscription, and does not auto-renew. Simple. Focused. Built for the moment that needs it.
