For co-parents
Co-parenting runs on arrangements made in passing, by text, at a doorstep. When one of them goes wrong it is a child standing in a playground.
Why this one matters more
A missed handover is not an inconvenience, and a disagreement about who said what is not a debate anybody wants to be having in front of a child.
“I’ll pick Jack up from school on Tuesday”
Deliberately not a co-parenting platform
There are serious products for high-conflict co-parenting, with court-admissible logs and monitored messaging. If that is where you are, use one of those.
This is much smaller and much quieter: the arrangements, written down, with the exact times kept. Nobody is building a case. Most co-parenting is not a case, it is two people trying to get a child to football.
The tone is on purpose
The creature in the app is confused, not cheerful, and it has no opinion about which of you is right. Money, failure and disagreement get no jokes at all.
