Speedometer. Google map night mode.
Version 1.8 is currently in beta development.
From version 1.8 you can apply a night style for the Google map. Apple map has always supported it, as users and developers we don’t have control over when it is applied exactly.
Night mode for the Google map makes night driving quite safer:
To apply, tap on a map settings button on the map or visit “Advanced settings” > “Map settings”. Pick Google map settings and setup the night mode. There is also an option to apply the map night mode automatically whenever the main screen night mode is active.
