When you open the app, it automatically detects your location and selects the nearest stop. From here you can choose the line, direction, vehicle type and stop you want and then press "Find" to display both your location and the vehicle you are looking for on a map.
You can change your selection at any time above the map (or close the map to zoom in on your selection). Shake your phone to reset the app. The "Where's the bus?" app works for all Västtrafik vehicles (except trains) throughout the Västra Götaland region.
The "Where's the bus?" app is available for iPhone and Android. Download it from the App Store or Google Play.
