A problem with these types of "crime news" "neighborhood" "snitch" "nanny" "home cam alert" apps, beyond the spyveillance permastorage datasharing etc... is that they are purposefully injecting mass amounts of abject subconscious fear FUD and propaganda steering into their userbase, then portraying themselves as saviour, plainly advertising Fear and Saviour as the solution in their marketing pitches, growing people's state of mental weakness and dependency on them as each month of service goes by. If companies like these want to sell a feelgood emotional support apps, fine, but be honest about it, and what they can and cannot do when the shit hits the fan. If you're in developing, imminent, or active harm to person or property... depending on some "app" company to save you in those times... is not going to help, at that point they're only there to mop up after the fact. Use 911, or call and message friends, all of which have delay. Broadcast scream to P2P in the area, carry a weapon, run away, fight back, and... use your brain to both get out of and avoid getting yourself into those potential problems in the first place. Funny you don't see those apps doing that... teaching people confidence, self defense, avoidance, situational awareness, preparation and planning, buddy system, etc... A lot of apps will have interesting use cases in this field. But when it matters, you aren't going to be thinking about how to fuck with your phone... your primitive fight or flight brain will have already decided for you whether to use it as distraction, head bashing tool, or as an excess unbalanced weight to drop in flight.
