UrbanCyclr shows where everyone cycles in the cities around the world.
All you need is to START tracking while biking around and STOP traking once finished.
All track will show up on one map resulting a community bike heat map.
With this you can plan where to bike, assuming the others know it better and also useful for city planners to see where new cycle routes are needed.
As you cycle more and more cities will be added to the list with dedicated maps and posters that can be purchased.
Note: The constant GPS usage of the app can shorten the battery life.
