## What is Little Green Book?

Everything about your child, in one place.

If you do not have your child every day, the details of their life end up scattered. A bedtime routine in one text. An allergy in an email you never deleted. A teacher's name you are sure somebody told you once.

Little Green Book is somewhere to keep all of it, so you walk into your time together already prepared.

It works completely on its own. Nothing in it needs the other parent to join, or to agree, or to do anything at all.

THEIR WORLD

Daily routines, health and allergies, school, doctor and contacts, friends, and the clubs and activities they go to. In your words, in one place, ready the moment you need them.

YOUR DAYS

Set the days you usually have them, once, and the diary fills itself in. Change a single weekend without touching the pattern behind it. See the week along the top, or open it out into the month.

PLANS

A hundred and thirty-two things to do with a child, from a wet Tuesday afternoon to a proper day out, and somewhere to turn one of them into a real plan with a date on it.

MEMORIES

Your own photographs and a few lines about the day. Private, and yours.

IF THE OTHER PARENT USES IT TOO

You can suggest a change, ask about a pickup, or pass on something practical. Nothing changes an arrangement until it is accepted, and ignoring a message leaves everything exactly as it was. Neither of you is in charge of the other, and neither of you is the guest.

Your memories, your plans and your private notes are never part of it. There is deliberately no button to share a memory.

IT ALL STAYS ON YOUR PHONE

There is no account, no sign-up, and no server. The app makes no internet connection at all, so nothing you write is sent anywhere, because there is nowhere for it to go.

When you do send something to the other parent, it goes as a small file through the sharing you already use: a text message, AirDrop, email. Your choice, every time, and still nobody's server in the middle.

You can keep the book shut behind Face ID or a PIN. You can save a backup file and keep it wherever you keep things. You can erase everything, properly, whenever you like.

Written in Britain, for parents here. Dates read the way you write them, and the things to do include the ones that only happen here.

One payment. There is no subscription, no free trial that turns into one, and nothing held back to unlock later.
