If you are in Valencia and you need to take a Bus, I recommend you try this app:
It tells you the upcoming buses time table, and also gives you the possibility to save your favourite bus stops and to check your bus card remaining trips, and to search bus stops by names, numbers or map.
It is highly recommended. It's made by a forum member, so please, if you want, rate this app in Google Play. It will only take a second and it will be very helpfull for the developer. The more five star reviews haves an app, the more users can find your app in the search results.
The application is free and has no advertising.
