A grocery list your whole family can actually share

How it works

1. 1

   Start a list - or just use the default

   Every family gets a default list out of the box. Add custom lists when a store or occasion deserves its own.

2. 2

   Add items your way

   Type them, set quantities and stores, assign them to someone, or ask the assistant to add them for you.

3. 3

   Pair devices so everyone sees it

   An encrypted device-to-device transfer shares the list with your family's phones. Items tick off for everyone.

From 'what's for dinner' to checkout

The grocery list usually fails in two places: items that never make it onto the list, and items nobody was clearly responsible for. FamiliaSync attacks both. The meal planner generates a dedicated shopping list from the week of dinners you planned, so ingredients land on the list instead of staying in someone's head. And every item can carry a name - when the milk is assigned to a person, the 'I thought you were getting it' conversation disappears.

Items carry the detail a real shop needs: quantities, the store you actually use, and a due date. Flag the essentials - the things you cannot come home without - and due-date badges separate 'needed today' from 'whenever someone is near the store'. Whoever ends up shopping sees a list that answers its own questions.

Sharing that doesn't need a shared account

Most shared lists are really shared accounts: an email, a password, a household of people logging into the same slice of somebody's server. FamiliaSync replaces that with device pairing. You approve an encrypted transfer between two phones, both devices confirm it, and the list lives on each of them. Ticked items tick off for everyone - without a server ever holding a copy.

Because there is no account, there is also nothing to hand over when a device leaves the family and nothing to breach on our side. The sharing model is deliberately small: the people whose phones you pair are the people who see the list.

Made for the supermarket dead zone

Supermarkets are where phone signal goes to die - steel shelving, basement car parks, thick walls. Cloud list apps spin or stall exactly when you need them. FamiliaSync's list lives entirely on your phone, so the checkboxes work in the freezer aisle the same way they worked in your kitchen.

It also makes the list fast in the way that matters mid-shop: add items with the on-device assistant while your hands are full, filter by store so a quick detour covers one list and not three, and trust that everything is already synced from the last pairing - no loading spinner between you and the milk.

Common questions

How do we share a list without accounts?

Device pairing replaces accounts. You approve an encrypted transfer between two phones, and the list lives on both. There's no shared login, no invite email, and no server holding your list.

Does the meal planner really fill the list?

Yes - the meal planner generates a dedicated meal-plan shopping list from the week you've planned, so ingredients make it onto the list instead of staying in your head.

Does it work in the store with no signal?

That's the point of offline-first. The whole list lives on your phone, so basements, dead zones, and airplane mode change nothing.

Can I keep separate lists for different stores?

Yes - custom lists sit alongside the default one, and items can carry a store label too, so a single trip is easy to scope.
