Home life rarely needs more task management. It needs less remembering.
Done When is a shared memory for the things you do together: walking the dog, changing the sheets, replacing a water filter, cleaning the coffee machine, watering plants, taking out the trash, and the small maintenance jobs that are easy to lose track of.
It is also a lightweight household task manager for roommates, couples, families, dorms, and other shared living. Rotation, Assigned, Anyone, and Private tasks give the record just enough structure without turning home into a project-management system.
Responsibility and completion stay separate. If Sam is up next and Alex helps, Done When records that Alex actually did it while Sam stays up next. The history reflects what really happened.
The interactive demo on the home page is separate from real household data. Changes made in the demo stay only in this browser.
