The route planner has the same design on iOS and Android devices.
You can access the Route Planner via the main menu → "Plan".
To get into the route planner, first go to the map symbol in the main menu. Either you can start right away by pressing and holding the map or you tap the green route symbol in the upper right corner.
By pressing and holding the map you can set individual waypoints. Alternatively you can enter a location or an address in the list view for the waypoints. The list view can be found in the upper right corner of the map under the button "A,B,C". Set the corresponding activity for your route in the menu at the bottom left using the drop-down arrow. Use the two arrows in the middle of the menu to undo or redo the last editing step.
