multiple trip monitor setup is a convenient method to monitor individual trips (stats such as distance, fuel consumption and cost, etc.) for single or multiple car profiles used on a single Android device
the app uses two predefined unbound trip monitors:
"Total" - persists statistics until manual reset by user
"This ride" - automatically resets statistics on each engine start to track current ride only
you can define additional trip monitors, such as trip monitor "A" ,"B", "C", etc. (each will persist statistics until manual reset by user)
to define new monitor(s), navigate to Settings → Dash → Trip monitors → Trip monitor management and add new trip monitor name(s)
moreover, you can bind trip monitor(s) to a profile, in case multiple car profiles are used, this will ensure that only the bound trip monitor(s) is active when a corresponding profile is active
in the dash main layout, simply manage the trip monitors using touch gestures as demonstrated in the video below (use swipe and long touch for contextual actions such as selecting a trip monitor, bringing up a action menu for enabling/disabling, resetting a trip monitor)
if you've bound the trip monitor(s) to a profile, make sure your active profile matches the bound profile, otherwise the monitor(s) will not be available in the dash
