TripSleep is a free mobile app designed to ensure that you never miss your stop while travelling on public transport. Developed by Konstantinos Reppas, a software engineer, this app uses GPS technology to wake you up before you reach your destination. The app is compatible with Android 9.0 and falls under the Travel & Navigation category with a subcategory of Maps & GPS.

The app is easy to use and works in three simple steps. First, you set a radius around your destination. Second, you check or search for your destination on the map. Third, TripSleep wakes you up once you enter that radius. This way, you can sleep peacefully on public transport without worrying about missing your stop.

The app also has a unique feature called "Athens Metro," specifically designed for commuters in Athens. OASA metro stations in Athens have poor GPS connectivity, which is why TripSleep created this feature. With "Athens Metro," you can click on your starting and destination points when you get in the metro and get woken up just before you reach your station.
