Open the app and you're caught up: whose birthday is coming, what they're into right now, what fits, and what's on their wish list. Each person keeps their own page current inside a private circle, so nobody has to chase the details. No feeds, no ads, no noise.

One page each: birthday, sizes, interests, a wish list. Kids' pages belong to their guardians. The person who knows the details best keeps them current, so you never guess a shoe size again.
One shared calendar carries birthdays, recitals and Sunday lunches, with invites and RSVPs inside your private circle. A warm heads-up arrives about a week ahead, so nothing slips by and nothing shouts.
The Gift Advisor turns sizes and interests into ideas that fit, and claims on wish lists stay hidden from the list's owner. The right gift, bought once, still a surprise on the day.
Here is what a quiet Monday looks like inside Know. One glance at any screen, then back to your day.
The family on their bench, a party hat on whoever's birthday is next, and what's coming and the to-dos in reach.
He's the one in the party hat. No rush, 12 days yet.

One shared calendar for birthdays, recitals and Sunday lunches, with RSVPs inside the circle.
Everyone's lists in one place, claims the owner never sees, and the Gift Advisor when you are short of ideas.
His day is the 18th. No rush, 12 days yet.
Know starts working the moment your people arrive, and they arrive through one link.
Your family, your friends, or both. A circle is private: only the people in it see what's shared. One link or code over iMessage or WhatsApp brings everyone in, with Apple, Google, or email sign in.
The Ellis FamilyBirthday, clothing, shoe and ring sizes, interests and a wish list, kept current by the person who knows them best. No group-chat guesswork, no asking someone's partner what size they wear. Any field can be marked private. Kids never get accounts: guardians keep their pages instead.
Shoe size · UK 5Claim something from a wish list and nobody else double buys it: each gift can only be claimed once. The list's owner never sees a thing, so the surprise survives all the way to the wrapping paper.
Claimed · owner can't seeFamily here, friends there. Each circle sees only what its members choose to share, and nothing is public, ever.
Claims on wish list items are hidden from the list's owner, always. One claim per gift, kept by the app, not by good intentions.
Children never get accounts. Guardians create their pages, approve sharing person by person, and can take it back in a tap. Gift ideas for a child go through their guardian first.
Birthdays, recitals and Sunday lunches on one shared calendar. Send invites inside the circle, collect RSVPs, and skip the new group chat. Shared to-dos keep the everyday running alongside.
Sizes and interests become real product ideas, and the in-app shop browser takes you from idea to basket without leaving Know.
A heads-up about a week before a birthday, in time to plan something good. Opt in, and it stays on your phone. No red badges, no countdown panic.
Know has no feeds, no ads, no tracking and no third-party analytics watching over your shoulder. What you share is visible only to the circles you choose, and the sharing rules are enforced in the database itself, not just in the app.
Start your circle and send one link. The dates, the details and the gifts settle into one private place. When the next occasion comes round, you'll be the one who already knows the size and already has the present.
