Obsession: The Way of Total Commitment Obsession is a goal tracker, habit tracker, and productivity app designed for people who want real discipline and focus. Most productivity apps try to motivate you with streaks, badges, and gamification. Obsession takes a different approach. It helps you commit to one goal and hold yourself accountable every single day. Inspired by the Bushido philosophy of total commitment, Obsession is built around a simple truth: Progress only comes from doing what you said you would do. If you want a productivity system that builds discipline, focus, and real progress, Obsession gives you the structure to follow through. How Obsession Works Choose One Goal Focus on a single objective instead of juggling endless to-do lists, habits, and projects. Set Daily Commitments Create the actions you promise to perform every day. These become your personal rules. Add Dated Milestones Turn long-term ambitions into a clear daily plan with scheduled tasks. Lock Your Commitments Once you enter the Way, your commitments become immutable. They cannot be edited, postponed, or erased. Daily Accountability Check-In Each day, every commitment is marked as either honored or missed. No partial credit. No excuses. Journal Your Journey Write daily reflections about your progress, struggles, and lessons in a private journal. Key Features One-Goal Focus System A productivity system designed for deep focus instead of scattered task lists. Immutable Commitments Lock your commitments so they cannot be changed once they are set. Daily Accountability Tracker Track whether you honored your commitments every day. Goal Planning with Milestones Break large goals into clear tasks and dated milestones. Private Journal for Self Improvement Reflect on your progress and build mental discipline through writing. No Gamification No streaks, points, badges, or dopamine tricks. Just honesty and discipline. Who Obsession Is For Obsession is built for people who want: • A serious goal tracker • A focused habit tracker • A productivity system that builds discipline • A daily routine planner built around one goal • Real accountability instead of motivation Whether you are training your body, building a business, writing a book, or changing your life, Obsession gives you a system that makes your promises matter. One goal. No excuses. The path or nothing. Legal Terms of Use https://obsession.app/terms.html Privacy Policy https://obsession.app/privacy.html

When did I last water the plant? Walk the dog? Call Dad? Restock the office snacks? When was the last time I did...everything? "Just Did" answers one question: when did I last do that? No streaks to maintain. No habits to break. No guilt-trip notifications. Just a calm, simple log of the things you do, with optional gentle nudges. A minimalistic approach to logging task completions and to-dos. ONE GESTURE, ONE LOG • Tap and hold a task card to mark it done. The card fills as you hold — a small, satisfying confirmation. No accidental ticks, no forms, no checkmarks, no fanfare. It's a different feel from every other tracker, and it's the whole point. SET A CADENCE, OR DON'T • Add an interval to any task — every 3 hours, every 4 days, every 7 days — and "Just Did" will gently remind you when it's been a while. Or skip the cadence entirely and just keep a record. Reminders are always optional, never pushy. SHARED SPACES, FOR ANY GROUP THAT NEEDS ONE • Create a Space and invite anyone with a 6-character code — your partner, family, roommates, dorm-mates, coworkers, project teammates, or a group of friends. • See who did what, and when. No assignments. No nagging. No leaderboards. Just a shared sense of "yeah, that's been done." • Use it at home, at the office, in a shared studio, on a trip — wherever a small group needs to keep track of the same tasks or to-dos. FREE FOR MAJORITY OF USE CASES • Unlimited personal tasks on your device, free forever. Spaces are free for up to 2 members and 3 shared tasks — enough for some groups. • The Pro upgrades are honestly optional. • Tasks Pro — full display customisation: background packs, premium completion animations, custom card colours, personalised colour scale. • Spaces Pro — removes the member and task caps. The owner pays; everyone in the Space benefits without paying themselves. PRIVACY BY DEFAULT • Personal tasks stay on your device. Shared Spaces only sync what's shared. Sign in with Apple, Google, or email — or skip sign-in entirely and use JustDid locally. Just Did is for anyone who doesn't want another habit tracker. No streaks. No guilt. No pressure. Just a quiet record of the things you've already done — alone, or together.
