Duo Speed is a very simple strait forward app. It will show your current speed in both mph and km/h at the same time. Nothing more, nothing less.

When traveling or emigrating to a country with a different speed system it can be daunting to keep track of your speed if you are not used to it.
The conversion from one to another is not that hard, but when driving it helps to see it in one instance.
