I have Google maps, Backcountry maps, and IGN maps on my phone already and I downloaded another one recently. There was a conversation about parking on the Forum recently and I realised then that I did not have one that showed individual streets clearly. I then found Windy Maps and find it very good, it's based on Openstreet maps I think and I am planning to test it out when I next want to find a parking place to sleep in my car. When I do this I park in plain sight, not stealthily where my car would stand out and be noticed.
