Doesnt work anymore

When I first downloaded this app, it was great, but now it just doesnt work anymore. Ive tried changing settings, turning up my volume, turning my phone on vibrate only, Ive set the alarm to go off while I was watching the app. All it does is show push notifications, which I cant hear or feel. Im guessing that an update went in that may have screwed things up.
