Is there an app for recording/streaming police activity currently available?

Someone told me about an app called Mobile Justice, but it was discontinued last year and I'm not seeing it on the google play store (I'm on GrapheneOS). I did some searching and read about ACLU Blue, which also doesn't seem to be available. Any suggestions? Is it possible Google/Apple is taking these apps down?

Side note, I recently had a meeting with some neighbors who all share many of the same concerns and would all be interested in an app like this. Some of them are tech-savvy, most are not. I think they're mostly iphone users. We're looking for something that will live-stream and save in the cloud even if our phone is taken mid-recording.

Edited to attempt to comply with rule 6.
