Coparent
Your record, on your phone, ready for court.
Coparent is a neutral, factual custody and communications log for separated parents. Every exchange, message, and expense is captured in a tamper-evident hash chain and exported as a court-ready PDF on demand. Solo-parent mode is first-class — the app works fully for one paying user even if the other parent never joins.

Your record, on your phone, ready for court
What you get
Coparent was built for exactly this.
The core features that make Coparent different from the generic alternatives.
Tamper-evident exchange log — every pickup and dropoff is hash-chained and server-signed
Court-export PDF generated server-side with full cryptographic chain included
Neutral coparenting messaging with optional AI tone-check (opt-in, never auto-sends)
Shared custody calendar with month and agenda views
Expense tracking with receipt photos and split balance (paid tier)
Chain verification screen shows record integrity at a glance
A look inside
See it in your hands.
A note from the studio
“The hardest constraint we gave ourselves was 'no deletions, ever.' A record that can be scrubbed is not a record. Everything you log stays, even corrections — they reference the original and append. That decision shaped every screen.”
How it works
Three steps. No account. No tracking.
01
Log what happened
Tap to record a pickup or dropoff — time, location, notes, optional photo. The entry is immediately appended to your tamper-evident chain and cannot be edited or deleted.
02
Communicate on the record
Send and receive messages inside Coparent. Every exchange is timestamped and stored. The optional tone-check suggests calmer phrasing before you hit send — you always review the rewrite first.
03
Export when it matters
Request a court-export PDF at any time. The server formats the full chained record with cryptographic verification details and delivers it via share sheet or email — ready for your attorney.
