Kidside
Kidside mark: two houses with a child between them

TWO HOMES. ONE PATH. CHILD FIRST.

Co-parenting, handled fairly.

Kidside keeps the custody calendar, schedule changes, messages and shared costs in one place that both parents can see. Nothing gets quietly edited after the fact.

What it does

Shared custody calendar

Set the pattern once (week on, week off, alternating weekends, or your own split) and both parents see whose day it is. Holidays and school breaks can sit on top of the regular pattern.

Swaps that need a yes

Ask to take days, or trade days back. A change only applies after the other parent approves it. Silence is not approval. Declines need a reason, and both go on the record.

Messages that stay put

Messages are timestamped by the server and can't be edited or deleted by either parent. If you ever need them, you can export the full history.

Side Check

Ask who has the kids on a date, or how many nights fall between two dates. Side Check counts from your schedule. It does not give legal advice.

Expenses and reimbursements

Snap a receipt, split it by the rule you both agreed to, and pay back through Venmo, Cash App or PayPal handles. Kidside never asks for a bank login.

Records you can export

Export messages, expenses, payments and the calendar as PDF or CSV, stamped with when they were generated. Handy for you or your attorney.

How it works

  1. Sign up. Use your email, Sign in with Apple, or Google. Set a 4-digit passcode so nobody else can open your messages if they pick up your phone.
  2. Set up your family. Add your kids (and pets, if they go back and forth too) and set the custody pattern.
  3. Invite your co-parent. Send a one-time link with a 6-digit backup code. Once they join, you both see the same calendar.
  4. Run the week from one place. Propose swaps, add events like recitals and appointments, log expenses and message each other. Grandparents or sitters can be given calendar-only access.
