Its OK
Its pretty good, but every time my phone updates during the night, the app shuts down and the alarm doesnt go off. Thats not good. I also wish it had some of the other bells and whistles such as a graphical display of my sleep. Regardless, Im going to have to search for a more reliable alarm clock/sleep app because I am relying on it to wake me up for work. IPhone 6 iOS 10.2.
