Set a backup because this works once a week at best. – Sleep Better: Sleep Cycle App Review

Set a back up alarm. When it works it’s great, but it’s been about two weeks since the alarm has actually made a sound. I’ll wake up the app asks me if I’d like to snooze despite the fact the alarm never went off. After being late for work a few times I’ve kept a backup alarm using the iPhones native clock app. It would be great if it worked consistently because when it works I enjoy the extra time in the morning.
