TriDo — 3 Daily Tasks

TriDo is a focus-first task app built around working memory research. Instead of overwhelming you with endless to-do lists, TriDo restricts each day to exactly three tasks — grounded in Nelson Cowan's working memory research (3-4 items) and the Zeigarnik Effect, which describes how unfinished tasks create ongoing mental load. The three-task constraint is a design boundary, not a suggestion. Every interaction reinforces completion over collection: swipe to complete, track streaks, visualise progress across a 12-month heat map calendar, and share completion cards with daily quotes from thinkers like Warren Buffett, James Clear, and Tim Ferriss.
