Sleep is about more than just measuring the time you were asleep. The amount of time spent in N3/4 (Deep Sleep) and REM sleep is very important. The author is using sleep cycle on his phone, which is not a good method of tracking sleep cycles. He says "their ability to wake me in “non-deep” sleep pretty spot on" - you're not in deep sleep in the morning anyway, or very unlikely. So any "app" has a good chance of waking you from REM or N1/2. We've been building a headband which monitors your sleep state, and uses sound to improve your sleep performance. Literally, improving the neurological function of your brain while you sleep. I used one of our early prototypes to win the Sleep World Championships (https://soundmind.co/blog/neurohacking-the-world-sleep-championships https://soundmind.co/blog/neurohacking-the-world-sleep-champ...). We're currently working on improving the fit and comfort before finalizing industrial design. You can find out more, and join the waitlist at https://soundmind.co https://soundmind.co

Just signed up for your email list. Please make sure the headband can stay on your head through the night. I have a chinstrap headband that I ordered on Amazon that falls off every single night, making it unusable.

  Can you link to the "chinstrap headband" that comes off? We have to make it appealing enough that people want to wear it, comfortable enough that you can sleep with it, and with enough stability to maintain a consistent EEG contact. What did you buy it for? What is it's purpose? If you're having trouble with a headband that is strapped to your head over your chin, I'm slightly terrified about what you are doing in bed. But if you can show me what doesn't work, it might help. We're testing in real-world situations, with multiple users, so we should have something that works for most people.
