Badger works with any calendar. To generate the calendar file from Badger to save on your Mac’s calendar (where it will then sync with your iPhone and iPad) all you have to do is:
1. Have your route open, then go to "More."
2. Click "Export to Calendar."
3. Then, click on the file in your download folder or at the bottom of the screen.
4. Apple Calendar should open. Choose the calendar you want to sync the Badger with. Then, click OK and you are all set.
