About

Cuboo

Cuboo turns focus into a journey, built around the hyperfocus technique. Start a session and you board a train. As you work, it glides across Europe in real time — forests, mountains, and coastline drifting past your window. Stay on track and you arrive at a new capital, earning a stamp for your passport. Get distracted, and the train waits. THE HYPERFOCUS TECHNIQUE Hyperfocus is the state of complete, single-task immersion — where time falls away and your best work happens. Cuboo is designed to pull you into it and keep you there: one task, one train, one destination, with no notifications to break the spell. Instead of a timer counting down, you have somewhere to be. HOW IT WORKS • Pick what you're focusing on — deep work, study, reading, creating, anything. • Choose how far you're going, and board. • Block the apps that pull you away for the length of the ride. • Focus. Watch the world go by. Arrive. WHAT'S INSIDE • A live train window with real moving scenery • An ambient sound mixer — train clatter, rain on the glass, forest, and lo-fi • App blocking that holds while you focus, powered by Screen Time • 24 European capitals to travel to, each with its own collectible stamp • A departures board, boarding pass, and passport that make focus feel like travel • Simple stats so you can watch your focused hours add up Whether you're studying for an exam, writing, coding, or just trying to stay off your phone for an hour, Cuboo gives your focus a destination. All aboard. ——— Cuboo Pro Cuboo offers an optional subscription that unlocks unlimited journeys and every feature: • Monthly — $3.99 / month • Annual — $18.99 / year (includes a 3-day free trial) • Lifetime — $34.99, one-time Payment is charged to your Apple ID at confirmation of purchase.
