Everything two households
need to stay in sync.

A shared custody calendar, expense splitting that settles itself, and the day-to-day logistics of raising kids across two homes — in one place both parents can see.

Free to use. About three minutes to set up.

Custody calendar

The schedule both homes actually agree on

Pick a repeating pattern and coparent expands it across the year, so nobody counts weeks on a paper calendar. Both parents see the same days in the same colors.

  • Built-in patterns: alternating weeks, 2-2-3, 3-4-4-3, 5-2, every-other-weekend, and full custody
  • Custom cycles when your arrangement does not match a template
  • Set the date your schedule starts, so it lines up with your actual agreement
  • Day swaps: propose a single-day change, and it only moves once the other parent accepts
  • Trips: block out a vacation range in one step instead of swapping day by day

Shared expenses

Who paid, who owes, and what it was for

Log a cost once and the running balance updates for both of you. No spreadsheet, no monthly reconciliation argument.

  • 50/50 by default, or set a custom split ratio per expense
  • Categories for the costs that actually recur — medical, school, activities, clothing, childcare
  • A running balance that shows who owes what, settled on your own terms
  • Recurring expenses for the predictable monthly ones
  • Insights that break spending down by category and by child
  • Receipt attachments, so the detail lives with the expense

Activities & logistics

The details that fall through the cracks

Practices, appointments, and school events belong to the child, not to one parent’s memory. Everything lands on the shared calendar.

  • One-time and recurring activities, tied to specific kids
  • Chores and household rules that carry across both homes
  • Document storage for custody agreements, insurance cards, and school forms
  • A message thread that keeps logistics out of your personal texts

Staying in sync

You find out without having to ask

coparent tells each parent what changed, so neither of you is the one chasing information.

  • Push notifications when the other parent adds an expense, activity, or message
  • Swap and trip requests, plus the accept or decline that follows
  • A handoff reminder the evening before a changeover day
  • Per-type notification preferences, so you choose what is worth interrupting you

Common questions

Do both parents need an account?

Yes. Each parent has their own login — you are never sharing an account or a password. One parent sets up the family and sends an invite link; the second parent joins in about a minute.

Can I start before my co-parent joins?

Yes. You can build the whole schedule, add your kids, and log expenses on your own. Everything you have already entered is there when the other parent accepts the invite.

What if our schedule does not match a standard pattern?

Build a custom cycle of any length and assign each day to either parent. On top of that, day swaps and trips handle the one-off changes that no repeating pattern can express.

Can the other parent change the schedule without me?

A swap is a proposal, not a change. The day only moves once the other parent accepts it, and both of you see the request and the response.

Where does it run?

On iPhone and iPad, and in any browser. Your data syncs between them in real time, so the calendar you check on your phone is the one your co-parent sees on their laptop.
