OnePage : Co-Parenting App

OnePage is the calm way for co-parents to stay on the same page - literally. One shared custody calendar, one message thread, one place for shared expenses and the records that matter, instead of five different apps and a group chat that never quite works.

Built for the day-to-day of co-parenting: knowing who has the kids, keeping a record that doesn't disappear, and communicating without it turning into an argument.

WHY CO-PARENTS USE ONEPAGE

Custody calendar
Set your custody schedule from a common pattern (2-2-3 rotation, week on/week off, every other weekend) or build a fully custom schedule. See exactly who has the kids on any day, with color-coded handoffs both parents can see.

Co-parent messaging
A private, timestamped thread with your co-parent. Messages can't be secretly edited or deleted, so there's never a dispute about who said what. Attach photos and videos right in the conversation.

Shared expenses
Log a cost, split it, and see who owes what at a glance. Approve or question an expense your co-parent submitted. No more screenshotting a banking app to prove a payment happened.

Info library
Medical details, school info and emergency contacts, shared and editable by both parents, with a full edit history.

Shared photos
A private gallery for photos and videos of your kids, visible to both parents.

Works solo
Every feature above works even if your co-parent hasn't joined yet — invite them whenever you're ready.

ONEPAGE PLUS
• AI-assisted tone check before you send a message that might read as heated — with a calmer suggested rewrite
• Expense splitting with approvals
• One-tap PDF export of your custody schedule, expenses and messages for any date range — handy for your own records
• Support for multiple children

OnePage doesn't take sides. It's a shared, neutral calendar and message log for co-parents — plain language, no legal jargon, and no subscription required for your co-parent to see the schedule you set up.

Every record — messages, expenses, schedule changes — is timestamped and can't be quietly edited or deleted, so what's written down stays written down.

Whether you're newly separated and setting up a custody schedule for the first time, or you've been co-parenting for years and are tired of juggling a text thread, a shared calendar app, and a spreadsheet for expenses — OnePage brings it into one page.

Download OnePage and get your custody calendar, co-parenting messages and shared expenses organized today.
