As soon as the Korter application opens, it shows the area that takes 15 minutes to walk or cycle, depending on the location. It must be ensured that the location feature is turned on in the phone. All you have to do is open the app and you will immediately see the surrounding area for 15 minutes. You can switch between walking and cycling or show both at the same time, you can also check to show the bus route system. There is also a bar in the app that can be dragged and shows different areas according to the number of minutes selected.
