.Parking is the best app to find your car, wherever you parked it, altogether avoiding the fines!
Save your car’s position and add a comment or a picture if you want. You can also indicate the maximum parking time in order to be notified and get back to your car before getting fined (Notifications are only available on devices running on iOS4).
Find your car using:
# The compass mode, which orientates the map (just like in Maps) to make finding your car easy,
# The augmented reality mode which allows you to walk while watching your iPhone,
# The directions to your car,
