Wont work

I saw a girl on YouTube on this app and was like hey that sounds like a good app because I can never get up so I think I will try it well I couldnt try it because whenever I downloaded it it opens pitch black then shuts out in about a 4 second range and idk if its the weather here or what +whenever I downloaded it it downloaded REALLY fast and that was a little sketchy to me but I uninstalled it then reinstalled and the same thing happened I was really hoping to use this app.
