iOS Notifications from Badger do a couple of things:
1. Notifications remind users about upcoming appointments. The timing of these notifications take travel time into account. You will get a reminder 5 minutes before you are supposed to start traveling to your next appointment. So if an appointment starts at 9 A.M. and has a 20-minute travel time, then you'll get the notification at 8:35 A.M.
2. Notifications remind users to check-in after an appointment. They will get the notification 5 minutes after the appointment end time. This notification only appears for appointments that are tied to accounts.
These notifications can be turned off individually in Settings. (They are turned on by default.)
