One person shouldn't have to remember everything.
In most households, one person holds all the information in their head. They know where the insurance documents are, when the MOT is due, what needs doing before winter. Their partner asks. They remember.
Roost is how you get it out of one head and into a shared place — so both people can find it, act on it, and stop relying on the one who remembers everything.

Research accepted by the British Journal of Political Science found women carry around 71% of a household's mental load. A Harvard study found the gap in cognitive household labour — remembering, planning, anticipating — is twice the gap seen in physical chores.
The mental load is not about forgetting to do things. It is about one person holding the map of the household in their head — and the other person not having to.
Roost does not fix this on its own. But getting the information out of one person's head and into a shared place is a start.

Vehicle vault. Service history. Both can check.

How household sharing works
Create a household
One person creates the household, invites others by email. They join on their own device.
Share anything
Each vault item, list, routine and note can be personal, shared with specific people, or shared with the whole household.
Real-time sync
Updates appear on the other person's device within a second. No manual refresh.
Both can edit
Shared items can be updated by any household member. Not just the person who created them.
Private items stay private
Not everything needs to be shared. Personal items are end-to-end encrypted and only visible to you.
Works across devices
iOS app and web app. Both people can use whichever works for them.
Household sharing is free. The free plan allows up to 10 items per section — upgrade to Pro for unlimited.
Common questions
What is the mental load in a relationship?
The mental load refers to the invisible cognitive labour of tracking, planning, anticipating and remembering everything a household needs — insurance renewals, maintenance tasks, shopping, admin. Research shows it falls disproportionately on one partner. Roost helps by getting household information out of one person's head and into a shared place both people can access.
Can couples share a household organiser app?
Yes. Roost's household sharing feature lets you invite a partner or housemate. Shared vault items, lists and routines update on both devices in real time. Either person can add, edit or complete shared items — not just the person who created them.
Is household sharing free on Roost?
Yes, household sharing is included in the free plan. Invite your partner or housemates and share vault items, lists and routines at no cost. The only limit on the free plan is 10 items per section — upgrade to Pro for unlimited items.
