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. 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, third-party analytics, or in-app purchases. FocusDensya is not an official product of any railway operator. It is not a real-time navigation, service-status, fare, or timetable app. Always consult official sources for travel decisions.

Stop letting links pile up — tuck them into your warehouse. Think Warehouse is a dead-simple keeper for the links you find, the photos you snap, and the thoughts that pop up. No account, no login. ■ Just toss it in Paste a link and it pulls the title and preview image for you. Shared a place from Maps? It sorts out the name, address, and link automatically. ■ Voice (new) Tap the red mic on Home and just talk. Filler words and false starts are cleaned up, to-dos and shopping become tidy lists, and "first, second…" turns into a numbered list. ■ Shelve it by category Make your own shelves — Music, Food, Ideas — and drop things in. It even guesses the right category for you. ■ This month's budget Jot down what you spend, add a receipt photo if you like, and look back at past months — subscriptions included as fixed costs. ■ Subscription reminders Register the things that leave your account every month and get a heads-up before each billing date. ■ Memos Shopping lists, reminders — pin, star, reorder, and browse by month. ■ Four languages Korean, English, Japanese, Chinese — switch anytime from the globe up top. ■ Only on your device Everything you save stays on your device. Nothing is sent to our servers. (Voice recognition is handled by Apple, and audio is never saved.)
