Works well if...
You only have one parking spot you are wanting to mark. Recently left my vehicle in the airport parking lot, marking the spot so I could find it upon my return 10 days later. then used the app to mark my rental car parking spot...app overwrote my personal vehicles spot so I had to rely on the tried and true key fob alarm button. Very disappointed. Will be looking at different apps after that experience.
