Train Stop Alarm

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; plays even while another app is playing music) ・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 ・Missed-Stop Savings: each time you answer "Saved me" to your home-station alarm, add the amount you choose (say, a taxi fare after missing the last train) to a virtual jar. No real money is involved ・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)
