Honeydo - The App Store's First Shareable To-Do Application
California based High Five Labs recently announced HoneyDo 1.46, serving as the App Store's first ever shareable to-do app, and even nick-named the "marriage saver app". HoneyDo was built to help primarily with joint domestic tasks that tend to create so much friction. From grocery lists to planning trips to paying bills to scheduling kids appointments/activities - Honeydo keeps your family in sync. It even offers fun, virtual gifts to motivate your collaborator and keep things light.
