Owning a car while living in the city is a pain. Parker aims to make your life easier by doing these three things:

  1. Alerts you to move your car before street sweeping begins
  2. Keeps track of when you parked & how much time is left in the parking meter
  3. Remembers your parking locations & provides directions to your car

It does all of this without any user interaction. It truly "just works!"
