I paid for the yearly membership, hoping to get insights into my sleep. Not even 3 months in and I'm uninstalling the app. I wish I had NEVER done the annual subscription. Some features are cool, like the sound tracking for snores. But the app does not register that I'm waking up (even when choosing how I feel waking up) and it doesn't work correctly on my watch. It constantly overrides my home screen and shows the set alarm whenever I turn on my watch. Even during the day after I've woken up.

I signed up for the free week and didn't really like it too much. The fact that it wants 7 nights of data to know how you sleep ends up paying for a year subscription. I have tried to cancel the subscription so I would not get charged and still was charged. It does not show in Google Play under manage subscriptions to cancel at all. My watch and phone do really well with my sleeping without this, and I am afraid I am out of money for something I will not be using at all.

Overall, it's good, but it's not recording very accurately. For instance, I had a lot of phlegm last night; Sleep Cycle did not pick up any of me clearing my throat, several times. I was awake more than asleep! Also, there's no place to write my own notes -just words to describe the day before.
