It would be interesting to hear your experiences on this, such as what apps you've tried and had fail for you in terms of productivity? I would agree with what you've said to a point, but this kind of statement needs expanding. For my wife and I, we're using Wunderlist (bought my Microsoft in 2015) and we can assign things to each other, star them as important, comment on tasks, leaves notes, set reminders, and so on. It's a... wunderful (har! har!) app and so far it's UI doesn't get in the way. I'm just waiting for the moment we hit the limitations of the free version and have to spend nearly AUD$130/user/year (USD -> AUD) to maintain its place in our household.
