Best coparenting app for kids schedules

[NewmemyselfandI]

Tired of being shouted at for not telling ex about something kids have, even if it was sometimes shared on whatsapp or verbally.
Need a way to add all on an app so there is visibility and we can communicate there objectively instead of crazy stressful messages and phone calls.
He is an narcissistic abuser who is using this to keep control and continue dragging me down, so it might not even work, but I need to try!

Following - have the same issue

Time tree is good

Shared google calendar not attached to your own email address - all the invited, appointments schedule goes in there and is available on demand. No adding him to invites or anything just post the schedule and wash your hands of it

I don't have personal experience but can you put it in your calendar and send him meeting invites? that way, it's not even like he can use the excuse that he didn't go into the app, or it doesn't work or whatever?

We have family wall. It's used to schedule dog care (kids are adults!)

App close and Family Wizard seem to come up alot on these threads.

The latter is court approved if you think that will be needed - but costs around £100 I think.

This is what I do.

Do you have iphones? Just put it in a separate calendar called “kids and invite him to it. He won’t be able to see anything else.

Thanks all this is helpful. I'll check the apps.
With Google calendar do you just create a family @ email and add things there and share login details or set up yourself and send invites to everyone?
We are on Android.

Well I tried the calendar but he doesnt accept invite and went mental becuse I went to lunch with kids while he at work and didnt tell him, so he couldn't take them out to dinner as they were full - when he hadnt agreed to see them in the first place.
I just dont think I need to say everything I do or plan to do with kids when they are with me, but obviously mention if a trip is coming or key dates...
He just will continue to abuse and find random things to blame me for and be confusing and unclear so can create his own narratives.
It's hell. I need a way to remove him from our lives or put strong boundaries legally but it's so painful and stressful to have to go this route when kids are older and things should be easy...
