Been using this one for a while.

I'm using a similar stack, Radicale on backend, DAVx5, and Calengoo as app.

Calengoo is not open source but you can buy it directly from the developer without Google integration. It's the only calendar app I've found that also does tasks properly, in that if I dismiss a task without explicitly marking it completed the notification will come back. It looks a bit strange out of the box but it has multiple themes and it's super configurable.

The one thing I don't like is that it uses a direct connection to CalDAV to mark tasks completed, instead of going through DAVx5 (not sure if it's a limitation in the Android chain or what).

yeah i do exactly this and it's very stable and unproblematic. has made a significant difference in my life

If super productivity + nextcloud ends up not being a good fit, i'll give this a try, thanks :)

Oh nice, it has a sync system with nextcloud !

For anyone wondering, I'm still using Super Productivity (though only a small part of its features) so far and I love it so much.

The sync with nextcloud is clean, and most importantly the way you add tasks is very todoist-like which is awesome.

You can self host habitica?? :O

Hadn't heart about ntfy, looks great for future projects, thanks !

Jtx notifications are always on time and sticky if you want.

Must be something wrong with my HA or my phone, I cant get notifications to work.

Well... I never got any notification 🤔 did you have to set up something specific?

Looks like I got work to do this week end

If only you had an app to list all the things you need to do 🤔
