Struggling to get started? Stop scrolling and start firing. Dopamine Cannon turns your mundane to-do list into a visceral, gamified experience. Instead of ticking boxes, you are loading artillery. Instead of "selecting" a task, you are spinning the cylinder of a high-caliber productivity weapon. How it Works: 1. Load the Armory: Add your micro-tasks (e.g., "Drink Water", "10 Squats", "Wipe Desk"). 2. Spin the Cylinder: Swipe left or right to randomize your target. The app learns what you avoid and helps you tackle it. 3. Prime the Cannon: Physically drag down the heavy bolt to load the mechanism. Feel the haptics build up. 4. FIRE: Release to lock in your task. The cannon fires, and your 5-minute focus timer begins. 5. Earn Dopamine: Complete the mission to earn points and track your "Combat Record." Key Features: 1. Satisfying Physics: Heavy haptic feedback and fluid animations make every interaction feel mechanical and powerful. 2. Weighted Randomization: The smart cylinder prioritizes tasks you haven't done in a while. 3. Combat Record: Track your daily, weekly, and monthly performance with detailed stats. 4. Focus Timer: A built-in "Fuse" timer locks you into the task until the mission is complete. 5. Dopamine Score: Watch your score rise as you build momentum. Don't just do your chores. Annihilate them.

The hardest part of having ADHD isn't understanding what to do โ€” it's starting. JustStart is built around one simple truth: the smaller the first step, the easier it is to begin. Break any task into pieces small enough to actually start, then use a body doubling timer to keep your focus going. TASK BREAKDOWN โ€” START IN 3 SECONDS Add a task, hit "Break It Down," and JustStart splits it into micro-steps you can actually begin. No more staring at "write report" on your to-do list. Instead: "open document," "write one sentence," "find one source." The first step is always achievable. BODY DOUBLING TIMER Body doubling is one of the most effective focus strategies for ADHD brains โ€” working alongside someone else (even virtually) dramatically improves task completion. JustStart's body doubling mode pairs you with focus sessions so you're never alone in the struggle. HYPERFOCUS ALARM ADHD hyperfocus is a double-edged sword. JustStart's hyperfocus alarm gently interrupts you after a set time โ€” reminding you to eat, move, or switch tasks before hours have vanished without you noticing. ADHD-FRIENDLY DESIGN No overwhelming dashboards. No endless lists. JustStart shows you one thing at a time โ€” the very next step you need to take. Minimal visual clutter, high contrast options, and large touch targets make it accessible when your brain is already at capacity. FOCUS TIMER WITH FLEXIBLE INTERVALS Whether you prefer 25-minute Pomodoro blocks, 10-minute sprints, or custom intervals, JustStart's focus timer adapts to how your brain works โ€” not how productivity gurus say it should work. WIDGET โ€” YOUR NEXT STEP, ALWAYS VISIBLE The JustStart widget shows your current task's next step directly on your home screen. Glance, tap, start. No unlocking, no navigating, no decision fatigue. STREAKS BUILT FOR ADHD BRAINS Traditional streak systems punish one bad day and reset everything. JustStart's streak system is forgiving by design โ€” rewarding consistency over perfection, and celebrating effort rather than output. REMINDERS THAT ACTUALLY LAND Smart, non-repetitive reminders that vary their message and timing so your brain doesn't tune them out. Because the fifteenth identical notification is invisible to an ADHD brain. JustStart is for adults and teens with ADHD, ADD, or anyone who struggles with task initiation, executive dysfunction, time blindness, or chronic overwhelm. You are not lazy. You just need a different kind of start. Free tier: 10 active tasks, basic focus timer. A subscription unlocks unlimited tasks, body doubling sessions, full focus history, custom hyperfocus alarm profiles, advanced widgets, and detailed productivity insights.
