Stay focused. Watch it grow.
In DevelopmentReef turns focus sessions into a living coral reef. Start a timer, put your phone down, and your reef grows with every session you complete — leave too soon, and it wilts. Earn Pearls to unlock new coral and fish, build daily streaks, and turn staying off your phone into the most satisfying part of your day.
That's the whole session — no complicated setup, just focused time away from the screen.
Complete a session and watch new life take hold. Leave too soon, though, and your reef wilts — real stakes, not just a countdown.
Every completed session earns Pearls, which you spend to unlock new coral and fish for your reef.
Keep coming back and your streak grows alongside your reef — turning focus into a habit, not a one-off.
Turn staying off your phone into the most satisfying part of your day.
