Based on how you are using Bouncie, you may want to be notified when trips begin and when they end. The start of a trip is triggered when a vehicle is turned on, and the end of a trip is triggered when a vehicle is turned off.
Creating Trip Start and End Alerts
Select Notification Settings from the Options Menu [•••], then choose Trip Start and End.
To be alerted when trips start, toggle the button on.
To be alerted when trips end, toggle the button on.
You can reverse either of these actions if you want to stop receiving these alerts.
