Just search for local star parties in your area. Although, be willing to bend the definition of local depending on how light polluted your area is. My local is 4 hours away. Also, some colleges have viewing nights available. Even in light polluted areas, you can still see things for public viewings. They just suck for anyone wanting to image.
There are tons of sites listing them, but I doubt there's an absolute exhaustive list as it's all self-reporting to each of the sites. Your app idea would just be another in a list of places, sort of like the xkcd app about yet another standard.
