Nobody has to police it.
The turn moves on by itself, so nobody has to play referee.
Whose turn was it to clean the bathroom this week, again? Same question in the flat group chat, every week. Someone has to ask. Someone feels called out. Nobody enjoys it.
From then on, the turn moves automatically every time someone marks the chore done. Whoever is up is shown first on the chore, with a darker ring around their avatar: no group-chat nagging, no spreadsheet someone has to maintain.
The turn moves on by itself, so nobody has to play referee.
"Tackle today" at the top shows what's yours right now, and whatever is falling behind sits first in its room. Open a chore to see its status: red, amber or blue.
Set up a separate chore per space (bathroom, kitchen, hallway) with its own interval. Not everything needs the same frequency.
In turn. Everyone sees it. Nobody has to say it.
Creating and using a chore schedule yourself is free. Sharing it with your flatmates, so the rotation actually works across the group, needs Premium: that applies as soon as more than 1 person is in your household. Premium costs €3.99 per month or €39.99 per year (incl. VAT), for the whole household. New households automatically get 14 days of Premium free, with no payment details, so you can try it with your flatmates. After that it is your choice; nothing is charged automatically.
