Stoppi is a stop timetable app designed to work with the Turku region public transport, though you may find it useful in other Waltti-region cities as well. The app includes the following features:
-It displays nearby bus stops and their real-time timetables
-It shows you the routes and and the locations of upcoming buses (locations available only in the Turku and Tampere regions)
-Your favorite stops can be saved and opened automatically when you open the app near your stop (see app settings).
