Your list tells you what to do. Not what to do first. Primora is a calm, fast iOS planner built around one idea: not every task deserves your time. Some matter today. Some matter tomorrow. Some are just pretending to be urgent. Most to-do apps treat everything the same. Primora doesn't. HOW IT WORKS 1. Brain dump Drop everything in — work, life, ideas, errands. No structure required. Your head's not a to-do list. 2. Sort what matters Move tasks into four quadrants. Two questions decide everything: is it urgent, and does it matter? 3. Do what matters first Your day reorganises around what actually moves you forward. THREE WAYS TO THINK Primora ships with three label styles. Pick the one that matches how you already think: - Critical · Focus · Distraction · Dump - Do It · Schedule It · Delegate It · Delete It - Urgent + Important · Not Urgent + Important · Urgent + Not Important · Not Urgent + Not Important Switch anytime. Your tasks stay where they are. DESIGNED FOR ATTENTION, NOT AGAINST IT - Two home screen widgets, see what matters without opening the app - Smart reminders, six trigger types, off by default - Projects organized by emoji, not folders - Native iOS, built in SwiftUI - No ads, no upsells, no streaks, no engagement traps BUILT FOR Founders, freelancers, designers, PMs, students, parents — anyone who's ever opened their to-do app and felt more overwhelmed than organised. If your day is full of tasks but your priorities are unclear, this is for you. WHAT PRIMORA ISN'T Not another productivity system to learn. Not a habit tracker. Not a calendar. Not a Notion replacement. Not gamified. It's a planner. It helps you decide what to do first. That's the whole app. Made with care. Built for clarity.
