You can download bycyklen.dk to your Android mobile phone - it adapts to the mobile format and works as an app. The phone in this example is a Samsung phone - there might be slight variations in other Android phones.
Open the browser on your Android phone (Internet, Google, Internet Explorer, Firefox, for example).
Go to bycyklen.dk.
Click on the "dots" that are marked with the green circle in the top right corner of the image below.
Select "Add shortcut on home screen" in the menu (marked with a green circle on the picture below).
Bycyklen.dk has now been added to your mobile phone and can be used as an app. Here you can find available bikes, make reservations (when you're logged in) etc. - just like when you use bycyklen.dk on your computer.
