This is a good idea, because some of us don’t have friends or family always available to call us. Also, I work every Saturday and I have to walk home in the dark, at night, and I can’t expect my friends or family to call me every single week on a Saturday night.
Why don't you just call your parents or your partner and tell them where you are and if they don't hear from you call 911? I would rather alert someone physically than rely on a crappy app to do it for me.
Plus this will have so many false alerts when people forget to check in on themselves after they've exited a dangerous area. Give me a break. This is a stupid idea.

It isn't an app yet, at least not on iOS
It can totally be used for blackmail too.
