Shaperunner is a free Android app developed by Ramboll, designed to make running in urban environments more fun. As the title sponsor of the Ramboll Stockholm Half Marathon, Ramboll collaborated with engineers and city planners to create a series of pre-programmed running routes for the app.

The running routes in Shaperunner come in various lengths, difficulty levels, and shapes, making them enjoyable to run and share with others. It's a great app for those who love to run and explore the city at the same time. However, it's important to note that the GPS positioning feature can quickly drain your phone's battery, so remember to close the app after use.
