The default working mode of the tracker is unable to be changed.
If you would like a more frequent tracking interval you can use the "Live" tracking option on the main map screen which puts the tracker into a temporary mode that updates the tracker's location every 10 seconds for a duration of 10 minutes. After this 10 minute interval it reverts back to its default mode settings of either "I am out" and "At Home".
Using Live tracking mode will increase battery usage so we advise using it on an as needed basis.
