AcornSleep vs NapBest

Welcome to AcornSleep, a custom R90 sleep cycle recording tool based on Sleep by Nick Ritterhales, a better way to improve sleep and redefine rest. 8 hours is actually the average sleep time per person per night, but it is not a generally applicable recommended sleep time. Blindly chasing 8 hours and creating a lot of pressure has a very destructive and counterproductive effect on sleep. We need different sleep hours from person to person. No supplements, new mattresses or equipment are required. All it takes is your smartphone, plus our AI-powered software to work with you to come up with customized tips and recommendations to personalize your sleep journey for better rest. 4 Reasons You'll Love Sleep Cycle. 1.

More Ambient Noise for Sleep - Ability to make your own personal mix of sounds so you get just the right amount of ambient noise. A good night's sleep isn't always easy to find, but it's the key to many things in your life. Stop mistreating yourself and those around you. Stop accepting the fatigue and lack of energy you've been feeling. Use AcornSleep to achieve the calm you need. Whatever you're doing right now, I want you to imagine the two of us on that island, trying to keep in sync with that biological process that's been around since the dawn of man.
