Ring's Neighbors app

I've found out the following about Ring's Neighbors app:

You can install and use the app without having any Ring devices:

Once you install the app and set up your account, you can also log in from a browser on a computer. You can view and post to your feed from either the app or your computer.

In the app you enter your address, which controls what messages you see on your feed. The default area for which you get messages is a circle of some large radius centered on your address. You can customize it to a smaller polygonal area by means of 8 draggable vertices.

I believe you can create an account at ring.com without using the app, but I think the rest won't work unless you set it up in the app first. When you login via a computer, if it doesn't take you directly to your feed, look for the link labeled "Neighborhood Web".

From what I've seen so far, unlike Nextdoor, the post topics are limited to safety, crime, and lost/found pets. Neighbors by Ring Community Guidelines indicates what kind of content is allowed.
