Train Stop Alarm
Wakes you before your station
$1.99 · Designed for iPad. Not verified for macOS.
Dozed off or lost in your phone? Silent vibration + full-screen alert as you near your stop. Handles transfers; Tokyo subway timetables give precise timing underground.
Missed your station because you fell asleep on the train?
Got lost in a book, a game, or your phone and rode right past your stop?
Train Stop Alarm wakes you with continuous vibration and a
full-screen alert as you approach your destination station.
No speaker sound — perfect for quiet train cars in Japan.
Ideal for travelers in Japan: set your stop, then relax —
even on unfamiliar lines, with transfers, and in subways.
■ Easy 3-step setup
1. Search for your destination station by name (English OK)
2. Check the alert radius on the map (300 m – 2 km from the station)
3. Tap "Set Alarm & Board" — then sleep, read, or enjoy the ride
■ Features
・Works with railways in Japan only — station search covers all of Japan
・Continuous vibration + full-screen alarm near your station
・Silent by design — never plays sound from the speaker
・Transfers: alerts at both the transfer station and your destination.
Choose the transfer station when there are several routes
・Toei Subway, Tokyo Metro & Yokohama Municipal Subway Green Line: identifies the train you are on from
timetables and alerts you right after leaving the previous station —
precise even underground
・Other lines: arrival-time prediction and GPS estimation keep the
alarm working in tunnels
・Live Activity: remaining distance on the Lock Screen & Dynamic Island
・Apple Watch: wrist taps and stop from your wrist
・Optional alarm sound through earphones only
(stops the moment they disconnect; never through the speaker)
・Save frequent stations with their own alert distance and start with one tap
・Station search shows prefecture and line names to tell same-name stations apart
・Choose the app language: Japanese, English, Traditional Chinese, Korean
・Works while the screen is locked or you're using other apps
・Your location never leaves your device
■ Notes
・Don't swipe the app away while an alarm is waiting (background is fine)
・On lines without timetable support, underground accuracy may be lower than
above ground — choose a larger alert distance if in doubt
・Location tracking uses battery; keep an eye on it on long rides
・Train timetables and positions: data from the Public Transportation Open Data
Center (Bureau of Transportation, Tokyo Metropolitan Government /
Association for Open Data of Public Transportation)
