Duet io
As husbands and fathers, we believe we're not alone in feeling acute pain in couples coordination - managing bills, remembering who's responsible to pick up the kids on Friday, planning birthday parties, remembering to text when you get home after a day at the office, buying birthday gifts, etc etc.
duet.io is an iPhone app with a shared calendar and shared task list that you'll use to stay coordinated with your family. Oh, and it comes with a virtual assistant that will actively try to find ways to help create more time for you.
