The missus and I would benefit from this -- I even got part way into my own Flutter app of similar functionality: she does shift work and I have to travel a lot. We're often not at home at the same time (or one of us is sleeping).
Things we'd get value from:
1. Has the dog been fed? (am, pm)
2. had his meds?
3. Should I expect to walk him in an hour? I may be lazy, but it's cruel to not get at least one walk a day.
3b. Long term, are we splitting the effort well? does one person walk him WAY more?
4. Did he not poop on two consecutive walks? do I need to watch out for illness?
"Oh, just communicate more, have you ever thought of that? Be better spouses" -- this is* us communicating, to take the best care of our dog :)
*he averages 2x 1.5hours per day + 2x 30min training sessions.
