> Can you tell me more about them? They both claim to "improve sleep" but their marketing site doesn't really say how.
For Dreem, there are a few ways it's intended to improve your sleep:
- Directly: It applies "stimulations" to "enhance" your deep sleep. These are sounds that are meant to intensify certain kinds of brain waves. I don't know much about them and can't say that they've improved my sleep quality.
- Education: In addition to simply showing you how much you sleep (which I find immensely useful) and how well you sleep (duration, stages of sleep, every single time you wake up during the night, no matter how short), the mobile app includes what I can only call training programs that are intended to help you improve your sleep yourself. These range from the introductory "this is how to use the headband" to a full-fledged CBT course.
- Small improvements: The app has a sleep routine feature that reminds you with a mobile notification when it's time to go to bed and automatically sets the alarm in the morning. The alarm sound is produced by a bone conduction speaker embedded in the headset. You can allow the headset to wake you early and if you do so, it will try to find the least disruptive time to wake you within the allowed period. Finally, it can play various sounds through the speaker to help you get to sleep, both ambient sounds (e.g. birds, waves, rain etc.) and guided-meditation type stuff.
> Keep in mind that all I want in the end is to have the numbers of when I was asleep, and when I was not. My goal being to have a graph of those numbers to see when I actually sleep. (eg. how much do my sleep times drift every day, how much do i sleep per week, etc)
For regular sleep at night it will do that perfectly. For random naps and dozing during the day, it won't be any help at all.
However the app is integrated with Apple Health, so if you wear something else that can detect those short dozes during the day, you can unite the two devices there.
