Became a dad 6 weeks ago. First night home, 3am, baby on one arm. I go to log a feed and the app wants a subscription. Next one shows me an ad. So I built my own. Free, no account, no ads. 🍼 One tap, one hand, in the dark Learns your baby's rhythm, not an average baby's Every health claim links to the AAP/NHS/WHO page it came from Scan a QR and both phones share one log One-page summary for the paediatrician visit Milk range for your baby's actual weight White noise + lullabies that survive the lock screen Works offline. Your data stays on your phone. I improve it every time I hit something I actually need at night. That's the whole roadmap. Stack: React 19, TypeScript, Vite, Tailwind, Radix, hand-built charts (no chart library), PWA, Cloudflare Workers + Turso for the optional sync. Basically all vibe coded with Claude Code. Source is MIT, judge freely. 💻 #buildinpublic #indiehackers

It's a pretty ridiculous concept, but it's been a really fun project. The
