📌 About the App
Do you listen to music, watch videos, or catch up on sleep while riding the subway with your earbuds in? Everyone has experienced that anxiety of constantly checking the screen or looking out the window, terrified of missing their stop because they couldn't hear the announcement. During crowded rush hours or when you're deeply seated, even doing that isn't easy.

Are your children now old enough to venture out of the neighborhood and take the subway to distant places? Do you worry if they can navigate complex subway lines, transfer correctly, and make it back home safely on their own?

Subway Station Alarm is here to do the watching for you.
Even while you are using other apps, it tracks your location in the background and delivers precise alerts (TTS voice, vibration, and banner notifications) one station before and exactly upon arrival at transfer and terminal stations.

🔒 Secure 'On-Device Processing'—No Internet Required
Real-Time Route Tracking: Subway alerts demand split-second accuracy. By processing everything directly on your smartphone instead of passing through an external server, we guarantee instant, zero-delay real-time alarms.

Complete Privacy Protection: Your real-time location data is never transmitted to an external server; it is kept 100% safe and secure inside your phone.

Zero Mobile Data / Wi-Fi Needed: Because it does not communicate with any servers, it requires absolutely no 4G/5G mobile data or Wi-Fi connection.
