Living together
Mornings with one of you, afternoons with the other, a handover at nursery pickup. Lily can switch at 15:00 while Nala switches at 19:00 — each dependent has their own times.
The week
One picture. Who carries what.
Simon and Katharina, with Lily and Nala. Colour is who is on. Violet is time together. Drag a handover to feel how the week moves.

The colour says who carries the responsibility right now. It says nothing else.
A real household, drawn by the same grid you get.

Try the sliders — handovers and the edges of together-time. Nothing here is saved; it is only the example.
Benefits
One picture. Everyone on the same page.
Parity draws responsibility as a state on a timeline — handovers, not calendar blocks you invent by hand.
Colour is who carries it
Green, orange, muted teal — equal weight. Never pink and blue. Violet is together-time, the bit you get back.
Height is the clock
An hour looks like an hour. Night is not compressed. The picture never lies about duration.
Width is which dependent
A calmer pet gets a narrower lane. The area you see is the load you carried — counted per dependent.
Relief fades, it never resizes
Nursery, school, grandparents, a sitter lower the effort. Responsibility stays with the colour underneath.
Lives in your calendar
Subscribe in Apple, Google or Outlook. Published weeks appear next to your meetings.
Invite is the product
One person sets up. The others join with a link. No second install, no shared password.
Use cases
Built for how care actually splits.
Same product for households under one roof and for parents who trade weeks across two places.
Living apart
One unbroken timeline across two homes. You see who is on, when the transfer is, and what the week actually looked like — without arguing from memory.
Pets only
Walks, feeding, overnight stays. Same lanes, same handovers. People use Parity for animals alone, and that is fine.
Three caretakers
A third adult — grandparent, co-parent, partner — gets equal visual weight. Up to three people on duty across the week.
What Parity will never do
- Never a fairness score. 60/40 can be exactly right.
- Never a comparison with other families.
- Never a colour that says one of you is behind.
- First names only. No birthdays, no required photos, no location.
Early access
One hundred founding households.
We are opening carefully. Start with email to claim one of a hundred founding places — free for now. Or subscribe to the newsletter if you only want to hear about bigger updates and the full release.
Early access is free. Feedback is welcome — warm notes, rough edges, whatever helps. We never judge how you split care.
Short questions
- Do we both need an account?
- One of you signs in with email and sets up. The others join through an invite link — no second password.
- Does it work for separated parents?
- Yes. It was built for one unbroken timeline, whether you live together or not.
- Can I use it for pets only?
- Yes, and people do.
- What if we stop?
- Export your data as JSON, or delete the household. Both take one click.
