The toilet paper is gone, so is the dish soap, and the coffee never lasts until the weekend. A list for a shared apartment differs from one for a camp or a barbecue in one way: it is never finished. There is no point at which you throw it away – only the question of who does the next run to the store.
Everyone opens the same link – no app to install, no account for each roommate or flatmate. For a one-off event with a date there are separate rules of thumb for groups and parties. This page is for everyday life.
A list nobody uses is deleted automatically after 30 days – with a shared household's list that practically never happens, because every real change resets the period in full. And after the shop there is no need for a new list: “Reset ticks” in the menu sets every item back to open, so nobody has to type in again what the household needs every week anyway.
Not just one person runs the list. For roommates a list without a PIN is often enough – then everyone with the link can add and change things. If you do want one, the whole apartment knows it; ticking things off works without it anyway.
Put “almost out” on the list while you are standing in front of the empty shelf. The note in your head is the one that gets lost.
Who usually buys the toilet paper, or which brand it has to be, goes in the item's note – that is where it is when it matters, not in last week's group chat.
Unlike a big shop for one event, this is rarely about food for one person – it is about what belongs to the whole household. A split that has proved itself in practice:
Household
Toilet paper, bin bags, paper towels, dish soap
Cleaning
All-purpose cleaner, sponges, bathroom and toilet cleaner
Shared kitchen
Oil, spices, coffee, tea, sugar, salt
Everything else
Batteries, light bulbs, compost bags
Categories can be renamed, reordered or deleted at any time – the split above is a starting point, not a rule.
