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.

Nurrow

Nurrow is a focus timer with a pet that grows when you do. Pick a length, 25 minutes, an hour, whatever fits, and hit start. Your pet settles in beside you while you work. When the session ends, you've earned shards: the currency you spend on eggs that hatch into new pets to keep, name, and collect. It isn't a punishment system. Skip a few days and your pet gets a little glum, but it perks back up the next time you sit down. It's there to make starting feel less like work and more like showing up for something that's waiting on you. WHY IT WORKS Most focus apps stack timers on top of guilt. Nurrow flips it: the reward is small, frequent, and tied to something that feels alive. You're not chasing a streak for its own sake; you're trying to hatch the next egg and see what's inside. FEATURES • Focus and Chill modes, pick the pressure that fits your day • Customizable timer for Pomodoro, deep work, or study sprints • Hatch eggs and grow a collection of 100 pets, common ones hatch fast, rare ones take real focus time • Pet Home, a cozy room to visit and decorate while your pet roams on its own • Share your hatch reveals as a card with friends • Six cozy habitats to choose and unlock • Journal your sessions and track real focus hours • Ambient sounds: rain, café, nature, lo-fi • Local notifications only, no account, no login, no tracking OFFLINE BY DEFAULT No account. No email. Your data lives on your phone. Terms of Use: https://nurrow.app/terms Privacy Policy: https://nurrow.app/privacy
