Automatic remembers where your vehicle is parked. When you park in a garage, it can be helpful to take a photo of the level or area sign you parked in. When you park at a meter or limited time zone, the timer lets you set a reminder for yourself, so you don’t get a ticket.
Of note: the parking photos sync across all phones signed into an account, while the timers are local to only one phone. This means that timers can work even if you’re offline and don’t have reception.
