A crowded lot can turn the end of an errand into an unwanted scavenger hunt. A smartphone can remove most of the guesswork by saving the spot where a trip ended and then providing walking directions back.
PCMag's guide starts with the mapping apps many people already have. Apple Maps can mark a parked car when an iPhone disconnects from a vehicle's Bluetooth system or CarPlay, while Google Maps lets a user save a parking location manually. The saved pin can then be opened for directions.
Dedicated parking apps extend that basic idea. Depending on the app, a driver may be able to attach a photo, note the floor or row of a garage, start a parking-meter timer or share the location with somebody else. Those details are useful when a GPS point alone cannot distinguish between levels of a structure.
The important limitation is that a saved parking location is not the same thing as a tracker installed in a vehicle. It records where the phone believes the car was left; it does not continuously report where the car moves afterward. GPS can also drift, and indoor garages may weaken the signal.
For the simplest setup, save the location immediately after parking and add a photo or note when the surroundings are ambiguous. The feature works best as a memory aid, with signs, floor numbers and landmarks supplying the last few feet of navigation.
