Dopamine Cannon
Read full descriptionHide full description
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. Download Dopamine Cannon today.
