Wren : Baby Log for Two

Wren is the baby tracker two parents keep together. Log a feed, a diaper, a nap in two taps — and it appears on the other parent's phone within seconds, each from your own iCloud account. No shared account, no server, nothing to set up.

Built for one-handed use at 3 a.m.: big buttons under your thumb, an impeccable dark mode, and everything you need at a glance.

TWO PARENTS, ONE BABY • Share a baby between two separate iCloud accounts with a single invitation • Everything each of you logs syncs automatically • Private by design — your data lives only in your iCloud, never on our servers

LOG IN TWO TAPS • Breastfeeding with a live timer, left/right side, and a one-tap switch • Bottle, diaper, sleep — the four essentials under your thumb • Pumping, notes, bath, temperature, medicine, visits, weight, height, head circumference • A running feed or nap stays on your Lock Screen and in the Dynamic Island — switch side or stop without opening the app

SEE THE RHYTHM TAKE SHAPE • "Last feed 2h40 ago" at a glance • Every day as a 24-hour strip, growth curves, daily patterns • We record — we never judge. No clinical percentiles, no coaching.

GENTLE REMINDERS (optional, off by default) • A quiet nudge if a feed or sleep timer is still running • Per-baby reminders for meals, weigh-ins, or a daily medicine

ON EVERY SCREEN • Home Screen and Lock Screen widgets • Apple Watch app and complications • Siri Shortcuts — "Log a diaper", "When was the last feed?" • Export everything as a spreadsheet (.xlsx or .csv) • Multiple babies with quick switching (twins welcome)

FAIR, SIMPLE PRICING Free forever for the essentials. A one-time purchase — never a subscription — unlocks unlimited history and the Apple Watch app. Buy once, both parents are unlocked, Family Sharing included.

What we'll never do: no ads, no data collection, no account to create, no social feed, no medical advice. Just the two of you and your baby.
