Update - still not fixed It does what they say it will but there is a bug they haven't fixed. And there workaround doesn't help either. When using an exact wakeup time a very irritating bell song goes when the music starts. The recommended turning Do Not Disturb on. This does nothing. I've paid for the year and can't get a refund. Hopefully they'll get off their rears and fix that soon.

Shouldn't be available. Half-baked product shouldnt even be in beta. Not worth purchasing the full version. App turns on at random and just loops. Every time I try to close it, it just reopens and starts trying to analyze my sleep. I have the alarm set for 5:30AM and usually go to bed around 10/11PM. However, in the middle of the afternoon, when I'm not even on my phone, the app just loads spontaneously and there is no way to shut it of. I swipe up to stop and it just keeps looping back.

In fairness this app is limited by the quality of the device it's being used on. Customer service was top notch. But tracking sleep via noise is in concept, a poor choice. I could lay quietly and the app would not realize I wasn't asleep. I could also toss and turn and the app may think awake. Also noise is noise and differentiating sounds 1ft away from 3ft away or from external sources would be rather challenging. If not impossible. The app is guessing at best.

We appreciate your thoughts on this and have shared it internally. There's also the option to choose motion detection (accelerator mode) instead of sound. Please email us at: support@sleepcycle.com so we can tell you more or help.
