Bottle Duty
🎓
You graduated 🎉
The bottle days are done — nice work. The book stays right here whenever you want to look back.
Bottle only. That's the whole app.

The other parent opens Bottle Duty, taps “Join with a code”, and enters:
——————
Look
Pick a skin for this phone. It applies instantly and lives on this device only — everybody in the book picks their own.
Babies in this book
Each baby keeps their own clock, totals, and alerts. Fix a name or birth weight here, or add a sibling when they arrive. What the doctor said lives in the Doctor's Orders card right below.
Stamped on every bottle automatically — no extra taps. Combo feeding? You can flip a single bottle while logging it. Changing the default here drops a “Switched formula” marker in the history.
People in this book
Parents can change settings and manage people. Guests can log bottles and notes — that's it. New joiners start as guests; promote them here.
On your phone
Missed it at the front door? Same steps, right here — the icon is the real app, and bottle alerts only reach a phone that's running it from the icon.
Notifications on this phone
Real push alerts from Bottle Duty when a bottle is coming due or overdue — they arrive even when the app is closed. No texts, ever. On iPhone, add Bottle Duty to your Home Screen first (push needs iOS 16.4+).
Done with bottles?
When the bottle days are behind you, graduate the book: the due alerts stop, and the book stays here to look back on. You can always reopen it.
Your way back in
Bottle Duty has no passwords — this phone stays signed in with a key it keeps. On a new phone or browser, the front door's “Get back into your book” asks for the family code plus your recovery code:
————-————
Parents can also see it in People above — that's on purpose, so a parent can read it to you over the phone. Lose both codes and there's no way back in; a parent would have to re-invite you as a new member.

Become a parent
Got locked out of the parent seat? If you hold this family's code, you can claim a parent seat. The book will note it in the history — claiming a seat is never silent.

Log a bottle
Leave a note
A sticky note on the book — not a bottle. It doesn't move the feeding clock.
Done with bottles?
You graduating, or is something wrong?
Then we did our job. 🎉
Bottle Duty is free for the next dad because parents who made it through chip in.
Something's wrong
Got it — thank you.
We read every one.
You're in 🎉
This is your recovery code:
————-————
New phone or browser? This code + your family code is the only way back in. Screenshot it.
Forgot to save it? On any phone that's still signed in, it's in Settings → “Your way back in” — and a parent can see it in People and read it to you.
