If you would only like the automatic tracker to only track your business drives during certain hours each day, you can use the Work Hours feature. To enable Work Hours, tap the Mileage tab > Mileage Settings (gear symbol) > Work Hours > toggle switch on and set the hours during which you'd like the automatic tracker to track your drives.
The Work Hours feature lets you set multiple segments. So, if you need to add more segments of work hours in a day, click the (+) to add a different section. NOTE: Segments must be in order from earliest to latest.
When using this feature, all of your drives outside of your working hours are automatically tagged as Personal. So only drives inside your working hours pull into the New section of the Mileage tab for you to tag as Business or Personal.
