As most people who travel in trains know, it is still hard to get live-location and delay information in any easy manner. Though there are several train apps in the market, none of these apps solved this vital travel problem convincingly. This was because most of these solutions were relying on known technologies like internet or gps which is not reliable or battery draining during travel. So we wanted to disrupt this space with an entirely innovative solution by using cell-towers directly without internet or gps. This was the birth of “Where is my train”.

Using an “offline” approach is inevitable to make this possible. Since cell-tower switching inherently happens in every phone, offline cell-tower lookup can instantaneously bring location awareness to an android wear or a lock-screen widget with no additional battery impact. This opens possibility to several unique features like offline location-based alarm without needing location-services. Creating a fully offline solution has ...

This opens possibility to several unique features like offline location-based alarm without needing location-services. Creating a fully offline solution has been quite challenging as we also need all the trains’ schedules offline. When we decided to pack the 12K train schedules with their route information offline, the raw json size was “200 mb” which was impractical to pack on a smartphone. We got these packed in around 800 kb now !! Also we packed 5 million contextual cell towers for each user in just around 4 Mb (which is downloaded on app install). This was a key reason in creating a big fan-base since most competitor apps are nearly double our apk size and still rely on internet.

Since you are best among all the apps for live tracking in offline mode, i recommend you to build an app or device for women safety which can live track the location even when they are offline.
