That sounds... personal?

But our power users!!

Our household revolves around the amazing Tasks.org Android app. Originally, I would sync the tasks using a Baïkal server because I prefer lightweight solutions. But since then, I've moved on to Nextcloud because I sometimes need a desktop overview of our tasks (and enjoy the other functionality). Nextcloud Tasks is very similar to Tasks.org, which I prefer over Vikunja etc.

Simple shared task lists have worked very well to keep track of chores, shopping and other reminders

For taking notes, keeping recipes etc. I use Joplin

What's wrong with PHP? :) Baïkal was just recently updated and supports the newest PHP versions
