Cuboo

Read full description

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.

Read full description

Turn focused time into a railway journey. With FocusDensya, choose a direct route or transfer itinerary that fits the time you have and depart. Follow the view from the train, check your position on the map, and optionally add a quiet soundscape while you focus. When you arrive, the session becomes part of your history and stamp collection. Your first journey is free to try, and waiting-room focus is free forever. Explore baseline railway routes across Japan with bundled offline route and station data. Journey durations are source-based estimates for the focus timer, not actual train departure times. Some suspended, seasonal, and event services remain outside the supported scope. Map backgrounds may require a network connection. Features • A railway-inspired focus timer • Smart direct and one-transfer itinerary recommendations • Detailed routes, stations, tickets, and journey progress • Window, map, and third-person journey views • Six optional ambient soundscapes • Live Activities on the Lock Screen and Dynamic Island • Focus history, streaks, and a stamp collection • Optional Screen Time integration that shields only the apps you choose during a journey • Arrival notifications and recurring reminders • Private iCloud sync across your Apple devices Screen Time, notifications, soundscapes, and iCloud are optional. The core timer remains available if you decline them. There are no accounts, advertisements, or third-party analytics. Commuter Pass After your free first journey, a Commuter Pass lets you keep riding every line. • Monthly Commuter Pass: auto-renewing, billed monthly • Yearly Commuter Pass: auto-renewing, billed yearly • Lifetime Commuter Pass: one-time purchase, never renews Prices are shown in the app in your local currency. Payment is charged to your Apple Account when you confirm the purchase. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period, and the renewal is charged within 24 hours before the period ends. Manage or cancel anytime in Settings > Apple Account > Subscriptions.
