The author's complaints about the various solutions hit home. My wife and I tried a bunch of solutions for shared tasks and lists. Finally I found vikunja, put it on my home cluster, and it's been a game changer. We never run out of milk due to a lack of communication, and I have no excuse to forget the chore she asked me to get around to last week.

There really is a sweet spot between helping productivity and overcomplicating life, and most of these applications go for the latter. Glad we finally found something that works for us. I'm just sharing here hoping it'll help someone else.
