My partner and I are using Microsoft To Do to share multiple lists, like a shopping list and ideas for vacations, presents for the kids etc. We already moved from Google to mailbox.org for e-mail and family calendars, but shared tasks somehow can’t be synced to other apps. Do you have any recommendations for good apps where people can share lists, that also have a browser UI (so they can be used on a PC without installation)?


I built go-notes for exactly this reason. You deploy it on your server, then there is a nice web UI, android app, windows app and Linux app.
Multi user with live collaboration, so you can see each other typing in shared notes.

That seems exactly what OP wanted. Nice work.
