Everything a household has to keep track of, in one place — who's where, what's for tea, whose turn it is, and what's run out. Shared with exactly the people you choose.
Kerfuffle is in beta. New households are approved by a person before they go live, so there may be a short wait — that's deliberate while it's early. Joining a household that already exists is by invitation only; there's no way to let yourself in.
Every person has their own colour, and so does every kind of thing — school, work, medical, birthdays. One tap filters the lot down to just the people or categories you care about.
The side-by-side day view puts a column against each person, which is how you spot that two of you promised to be in different places with the same car.
An old tablet on the kitchen wall, always on, showing today at a glance: chore cards the children tap themselves, what's for tea tonight, and the shopping list as it grows. No signing in, no unlocking, nothing to find.
A child taps their own card, the star count goes up, and the routine stays in the order it actually happens rather than jumping about.
Put people into circles — grandparents, the school run, the babysitter — and choose, for each thing you add, whether it stays private, goes to the household, or goes to one circle.
You can link up with another family so the school run works, and they still see only what you have shared. Not your whole calendar.
The things you always buy add themselves back to the list each week, so nobody forgets the milk on principle.
Prices are remembered from last time, giving you a rough total before you set off — and the whole list copies out in one go for a delivery order.
Chores are built for children who can't read yet: a picture per job, big enough to tap, and a star when it's done.
Stars add up to whatever you decide they're worth in your house. It works better than saying teeth for the fourth time.
There's an assistant you can type at in plain English. It can add and move events, put things on lists, and answer questions about what's coming up.
It isn't magic and it doesn't run your life. It saves you tapping through four screens to move swimming to a Friday.
This is one person's home server, running a thing they built for their own house and a few friends' houses. That's the whole of it.
