ParkingMate

ParkingMate is a HarmonyOS-based atomic service that helps users remember where they parked their car. With a single button, it saves the current location using Location Kit and later guides the user back to that point using MapKit navigation features.

This app is designed to simplify your urban experience—no more wandering in large parking lots or city streets searching for your car.
