Great options, disappointing function

I have very mixed feelings about this app. I LOVE how many options it has, I.e. Length of time for sleep sounds & snooze, different toons, and sections for alarm, reminder, bed time & wake up time finders...but I dont actually like how it works. Biggest issue: alarm will only go off if app stays open. Sometimes I forget, especially trying to wake up and check apps and falling back asleep.
Also getting out of sections with up and down swipes are very difficult...
And says it will report data to Apple Health app but that has yet to work for me
