Free and Open Source Software

My wife and I have been struggling to find a decent app that we can use to check things off. Primarily, we’d be using it as a grocery list, but ideally I’d love for the same app to be able to handle her long-term “honey do list” projects, and for that one cloud-syncing is a must.

So far we’ve tried Apple Notes (buggy on her phone, but not mine), Google Keep (app won’t stay in the list when phone is locked. Also, privacy. All of a sudden we’re getting ads for stuff we’ve added; no thank you), and AnyList (company keeps all the decent features behind a paywall, so I don’t know if we’d actually like it).

Thanks for your thoughts!
