Lista - A To-Do List App That Stays Simple as It Grows

Lista is a to-do list app for people who want to organize life, not just a flat list — simple lists or larger projects, private or shared. Spaces, lists, and sections give everything a place, and you can filter all of it, a space, or a list down to just what matters. It all stays intuitive, with no setup. Built for iPhone, iPad, and Mac.
