TaskBlue turns your screen time into real ocean cleanup. Every hour you stay focused pulls real plastic from the sea, recovered by our ocean-cleanup partners. How it works: choose the apps that distract you. Hold the circle to start focus. They disappear until you scan your Focus Buoy. OCEAN IMPACT Every focus session pulls plastic from the ocean. Track the grams you collect, reach your monthly goal, and build your streak. FOCUS MODE Pick your distractions. Hold to activate. They disappear. FOCUS ON AUTOPILOT Manual: start a session whenever you want. Schedules: recurring focus times. Calendar: focus starts before important events. Location: focus starts automatically when you arrive at campus, school, or work. LEAVE ON TIME Set when you need to go and stay focused until departure. YOUR FOCUS BUOY The Focus Buoy is the physical NFC key to TaskBlue. You scan it to end focus, and it sets how much ocean plastic you recover each month. Available at taskblue.app.
