Just don't leave the vibrator on all the time and I'll probably not be looking at the app mostly be answering questions.
I enjoy going to abandoned places and just walking around naked. I often carry my purse and other stuff on me just in case which has my cell phone and pepper spray because I carry that stuff clothed anyways and where am I supposed to keep my car keys? In my pockets? It's been nice and freeing to walk around places like this naked. I always have thought about bringing a remote toy but I always leave it at home because often I'll come to places like this after work or like before/after eating out with friends.
