It is possible to modify the data set displayed on each of the data screens. This can be done independently for different sport profiles.
To modify a data screen set, click on the 'pencil' at the bottom left of the 'data' area visible on the first tab of the application.
In the screen setup screen, use the (+) to add data wherever you want, or the (x) to remove data.
By choosing (+) a list appears showing all the data available for display.
Note that some data requires the connection of a sensor to be visible (cadence, power, heart rate..)
Swipe the upper part of the screen to scroll and then modify the different screens of a given sport profile. Once you reach the last screen you can add a new screen by clicking on the '+'.
To edit your screens during an activity, first press pause to see the edit function appear.
