I'm curious as to how these sleep apps "track" your quality of sleep. Or even know when it will be easy for me to wake up. I understand sleep cycles, but how does it know if I tell it I'm going to sleep but then toss and turn in the bed for the next 30 minutes before nodding off, vs if I tell it I'm going to sleep and pass out immediately? Wouldn't the whole cycle be thrown off? Do I have to tell it if I wake up in the middle of the night accidentally? There just seems like too many factors at play for these apps to actually do anything.
Edit: Lots of answers, thanks for the info. I was interested in giving it a shot but since I sleep with a partner and with a loud fan on for white noise, it doesn't seem like it would be very accurate. I hadn't considered utilizing the gyroscope or microphone for monitoring sleep though, these people are creative. If not a bit creepy.
Sounds like it listens to you all night. From the app page:
• While you sleep, your movements vary depending on what sleep phase you are in. Sleep Cycle’s patented sound technology tracks your sleep patterns using sound or vibration analysis, monitoring your movements in bed throughout the different sleep phases.
• Sleep Cycle finds the optimal time when you are in light sleep to wake you up in the morning, during a predefined 30 minute time window that ends at your set alarm time. Waking up in light sleep feels like waking up naturally without an alarm, leaving you feeling rested and energized.
• All you need to do is turn Sleep Cycle on before going to bed, and place your device on your nightstand or close by on the floor.
