Doesn't work on iPhone 6s+ – The Rock Clock™ Review

I've done everything it says to do for the last week and it hasn't gone off once. I open the app and set it to sleep mode and it doesn't go off. I lock my phone but I keep the app open and running. Please fix this problem and make it work just like the normal alarms in the phone
