The custody calendar
Set the schedule once (alternating weeks, 2-2-3, every other weekend or your own pattern) and both parents see the same calendar, with each parent's nights.

Custody schedule, overnights, child expenses and messages in one calendar that both parents see the same way. Free: every feature, no trial that runs out.

From Monday's handover to the end-of-month report: all in one place, the same for both of you.
Set the schedule once (alternating weeks, 2-2-3, every other weekend or your own pattern) and both parents see the same calendar, with each parent's nights.

Ask to swap a weekend in the app: the other parent accepts or declines, and the decision is saved with the date and time.

Take a photo of the receipt and the amount and date fill in by themselves. Split 50/50 or by the share you agreed: the balance is always up to date.

Separate from everyday messaging. Sent messages can't be edited or deleted.

A PDF with the calendar, overnights, expenses and messages for the period you choose, with a SHA-256 fingerprint to check it hasn't been altered.

FamSync works best when you're both on it: each parent on their own phone, on the same calendar.
