Finally set up a #nextcloud server for the household. Hoping to replace several big-company and ad-based services with it.
File sync/sharing: straight-forward, works well across desktop, web and mobile apps. May need to add storage.
Next step: to-do lists. Looks like Tasks will do what I want (both personal & shared lists), but I need a good mobile app to use with it.
Then I need to experiment with Carnet. Already moved from Google Keep to SimpleNote, might keep going.
