A shared list and chore chart for roommates

Two problems in a shared flat: nobody knows what the house needs, and nobody agrees on whose turn it was.

One list the whole flat can reach

Everyone adds to the same list from their own phone. Whoever ends up at the shop sees all of it, and what they tick vanishes for everyone else — so two people do not come home with two bags of the same thing.

When someone arrives at a shop with things still on the list, the rest of the flat gets told. That is usually the moment somebody remembers the bin bags.

Chores that keep their own schedule

Set a chore to repeat and it reschedules itself when it is done, instead of quietly disappearing. Anything unclaimed can be taken with one tap, and the household page shows what each person has actually done lately — which settles most arguments without anyone having to start one.
