Here's a great app with property boundaries. You can see where you are and what property you're on. I assume it's not perfect in 100% of cases, but has been very accurate in my experience: https://play.google.com/store/apps/details?id=com.huntstand.core
Plus it's free.
It's a hunting app, but can be used for what you're looking for. It's called HuntStand. Shows you property boundaries, you can drop pins, etc.
