When someone asks what happened and when, you have the dates, the receipts and the math - calm and in one place.
CustodyBook is a private co-parenting log for separated parents: a visual custody calendar, shared expenses and clean monthly reports you can print or share with your lawyer.
COURT-READY PDFs
Every entry is dated, with its edit history, and every PDF carries a SHA-256 fingerprint so you can check later, at getcustodybook.com/verify, that the report hasn't changed since you exported it. The judge decides what is admitted. Not legal advice.
WHAT YOU GET
✓ See your parenting schedule on a visual custody calendar - 2-2-3, week-on week-off and other rotations at a glance.
✓ Log custody days and exchanges in seconds - dated and factual.
✓ Track shared expenses to the penny, with receipt photos and a configurable split: the app tells you who owes whom.
✓ Export a monthly report in a neutral, factual tone your lawyer will appreciate.
✓ Copy any month's summary as plain text, ready to paste into a message to your lawyer.
✓ Export your records as CSV whenever you want the raw data.
✓ Keep everything on your phone - no messaging, no shared account, no server holding your record.
FOR COURT PREP AND MEETINGS WITH YOUR LAWYER (new in 1.9)
✓ Change history on every entry: see what was edited and when.
✓ Entries logged more than 24 hours after the day they describe are marked "Added later".
✓ PDF reports with a timeline, a per-parent summary and a SHA-256 fingerprint in the footer, with your data attached — so you can later check that the report's data hasn't changed since you exported it.
✓ Photos show the date they were taken, when the photo includes it.
✓ Export history in Settings lists every report you created.
WHEN THE OTHER PARENT OWES YOU FOR EXTRAS
• Mark the date you asked the other parent for their share of a medical bill, school fee or activity. The monthly report shows every unreimbursed extra, how much, and how long it has been waiting.
• Add the time and place of each exchange or custody day - folded away, so a normal entry still takes seconds.
• The app warns you when entries are not backed up yet, so a lost or broken phone doesn't have to mean a lost record.
MADE FOR ONE PARENT'S RECORD
For separated or divorced parents who need their own reliable record. One-sided by design: the other parent never has to join, and your co-parenting log never depends on anyone else's cooperation. Just dates, facts and math - a calm record for calmer conversations.
WORKS OFFLINE. NO ACCOUNT. NO ADS.
• Everything stays on your phone - no sign-up, no cloud, no tracking.
• Works with no internet, anywhere.
