FocusDensya
Read full descriptionHide 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. 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.

Verdict
The clearest difference is in-app purchases: FocusDensya at none against 土豆ToDo's 2. 土豆ToDo's advantage is update cadence (daily vs every 2 weeks). On price, ads, device support and iOS requirement there is nothing between them.
