Great things are built one step at a time. Trajectory is the AI-powered goal planner and project tracker that transforms your biggest ambitions into a clear, week-by-week action plan with specific daily tasks. Stop staring at a blank page. Open Trajectory and know exactly what to do today. HOW IT WORKS: • Enter your goal: write a book, learn a language, launch a business, get fit, master a skill... • Our AI builds a personalized step-by-step roadmap across weeks • Complete daily tasks, earn XP, level up, and make real progress every single day FEATURES: • AI Project Planner: Generate a complete week-by-week roadmap in seconds • Daily Schedule: See all your tasks for today across every project • XP & Levels: Earn experience points based on work produced, not time spent • Leaderboard: Stay accountable and motivated by competing with others • Progress Tracking: Visualize your milestones and how far you've come • Streak System: Build momentum and consistency day after day • Multi-Project: Manage several long-term goals simultaneously A SMARTER APPROACH TO PRODUCTIVITY: Most productivity apps reward you for the wrong things. Pomodoro timers and time trackers apps measure how long you sit at your desk, not whether those hours are actually productive and moving you toward your goal. Trajectory is different: → You earn XP based on tasks completed, not minutes spent. Being efficient is rewarded. → Every work session is generated by AI to directly serve your long-term goal, no wasted effort, no busywork. → Instead of piling up disconnected daily tasks, Trajectory builds a structured roadmap so every action you take is a step in the right direction. SCIENCE-BACKED METHOD: Research shows that breaking goals into specific, actionable steps beats procrastination (Pychyl & Sirois), maximizes productivity and performance (Locke & Latham), and sustains motivation through small wins (Weick). Trajectory is built around these principles from the ground up. PERFECT FOR: → Entrepreneurs building a product, startup, or side project → Students tackling long-term assignments, dissertations, or learning goals → Writers, creators, and makers with big ambitions → Professionals working toward career milestones → Anyone struggling with procrastination, focus, or motivation → People who want to replace busywork with real, meaningful progress WHY TRAJECTORY: Goal setting without a plan is just a wish. Trajectory bridges the gap between ambition and daily action, turning months-long projects into simple, manageable steps you can complete every day. Whether you're working on personal development, a creative project, a fitness goal, or a professional challenge, Trajectory keeps you on track, accountable, and moving forward. Your goal is waiting. Start building it today, one step at a time. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
