Co-parent expense tracker for iPhone
Shared costs without the arguments
Most expense fights are really about missing records. Oya Shield keeps a ledger both sides can trust: receipts attached, splits applied consistently, and a dated history that answers questions before they become disputes.
A system, not a spreadsheet
Log it when you pay
Amount, date, category, who paid. A one-minute habit at the register replaces a weekend of bank-statement archaeology.
Receipts attached, not lost
Photograph the receipt into the entry itself. An expense with its receipt is a fact; without one it’s a claim.
Split by your rules
Percentage or fixed amounts, per your agreement. The math is mechanical, so it never has to be renegotiated at checkout.
Totals at a glance
Outstanding, settled, and this-month figures stay current, so settling up is an administrative step instead of a confrontation.
One record with your custody log
Money disputes braid into scheduling disputes. Expenses live alongside your incident log, so the whole history stays in one dated place.
Exports that end arguments
Share a clean, dated PDF of expenses and receipts with your co-parent, mediator, or attorney whenever it’s needed.
Every receipt, in its place
7 days free on iPhone. Expenses and your custody log together, always yours to export.
