Never worry about missing your stop again! Just tell Transit Alarm where you're getting off the train, and your iPhone will notify you when you're getting close. Since Transit Alarm is a GPS-based alarm, it will always know if you're running early, late, or right on time. You can even track your location in real-time and see how far you have left to travel! So go ahead- use your commute to get some sleep, focus on work or just zone out. Transit Alarm will make sure you know when you're approaching your station'. UPDATE: We have added thousands of new stations. To update your app, go to Settings and press the "CHECK FOR UPDATES" button at the bottom. This will add support for Amtrak, Caltrain, BART (Bay Area Rapid Transit), MTA Metro North, LIRR, MTBA Rail (Massachusetts Bay Transportation Authority), MARC Train (Maryland Area Regional Commuter), and Virginia Railway Express. A few useful notes: ----------------- - Going to sleep? Don't forget to turn your sound up! Transit Alarm will vibrate if your iPhone is on silent, but the audio alarm can be quite useful. - Transit Alarm will still work if the app is minimized, so you can set your alarm and forget about it.
