See daylight & dark hours at your destination. Plan safe trips, fully offline.
Read full description
Have you ever walked to a bus stop in complete darkness on a winter morning in Europe?
Sunrise at 8:40 AM. Leaving the hotel at 7:30. Map apps tell you the route — but not whether that route will be dark. Daylight Trip is a travel timeline that visualizes daylight and darkness at your destination, so you can plan a safe and comfortable itinerary.
■ See each day's light at a glance
The timeline's time axis is painted in a 4-color gradient: night (deep blue) → morning twilight → daylight (white) → evening twilight → night. Twilight (civil twilight) marks the boundary of "bright enough to walk outdoors without lighting." Just add your plans and instantly see which ones overlap with dark hours.
■ Inspect your whole trip in the Overview
The overview stacks one 24-hour bar per day, revealing every plan that sits on top of dark hours. Watching the white band of daylight shrink as you travel north is especially useful when planning winter trips to high latitudes.
■ 34,000 cities, fully offline
All sunrise, sunset and twilight calculations run on your device. City data (about 34,000 cities with population over 15,000, searchable in English and Japanese) is built in. Works in airplane mode and far from any signal. Time zones and daylight saving time are handled automatically and accurately.
■ Both ends of your flight, precisely
Transfers across time zones show departure and arrival in each city's local time — answering exactly "will it be dark on my way to the airport?" and "will it be dark the moment I land?"
■ Print it and carry it
Export your itinerary as a PDF: one overview page plus one page per day. Transfers are hatched and boundaries carry sunrise/sunset times, designed to stay readable even in black-and-white print. Hand a paper copy to your travel companions.
■ Packing checklist built in
Passport, charger, travel adapter — the travel essentials are already listed. Tap to check items off, watch the progress bar fill, and get "All packed!" when you're ready. Checks are saved per trip. Register your own regulars (tripod, motion sickness pills…) in My Travel Kit and reuse them on every trip. From itinerary to luggage, get trip-ready in one app.
■ Save as many trips as you like (New!)
Multiple business trips, a draft of your next holiday, a great plan worth keeping — switch between saved trips in one tap from My Trips. Packing checklists are managed per trip. Add notes like "ticket required" or "about 40 min by taxi" to plans and transfers — they appear in the printed PDF too.
