Lister is yet another list app. What makes it different is that your lists are stored on the cloud, allowing your family and you to maintain grocery lists, todo lists, chores, and whatever else you want to remember. Perhaps a list of movies to watch with your SO that you can both add to?

After downloading the app, type in your phone number. This will create a user profile for you. Add your friends to a group, and list away! All members of a group will have access to all lists and items on those lists.

Assign items to people in your group, allowing you to designate tasks. View your own assigned items on 'your list.'

This app is dedicated to my cat, who is always so great at reminding me to do stuff.
