Cairn creates a cleaning plan around the size of a home, the people in it, and how much time they can give each week. Its weekly board assigns jobs by day and shows estimated time, then adjusts estimates when household members record how long a job took. Monthly and quarterly checks, deep-clean tasks, a supplies list, and home or vehicle maintenance schedules are also included. A setup flow previews the first week before the household commits. The developer says each household gets 30 days free before choosing an individual Cairn membership or a bundle of related apps.
