Stresfri's multi-household mode was built for shared parenting. Your kid sees their whole week in one place, whichever parent's phone they're holding.
Each parent runs their own household; the kid's calendar aggregates both. Swim at Mum's, football at Dad's, no confusion.
Ticks, updates and reschedules land in Stresfri. Nobody has to type 'ok' seven times a day.
Wallet, budget, private events stay with each parent. Only the shared child rows cross the household boundary.
