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.

Abundant Customization Tips - A large number of rest suggestions customized for you based on your sleep cycle registration information, daily schedule and mobile phone usage frequency. 3. No additional equipment - Just turn on your phone every morning and record how you slept last night, the AI assistant will provide you with customized advice. 4. 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.

Living with narcolepsy means the day can turn heavy without warning. This app helps you stay ahead of it. It learns from your logged episodes when you're most likely to get drowsy during the day, and combines that pattern with live signals from Apple Watch (heart-rate variability, heart rate, sleep, daylight and activity) to estimate your current drowsiness risk β and warn you before a high-risk window. What you can do: See your live drowsiness risk β with a breakdown of why it's rising or falling Get an early warning before your predicted high-risk times Log sleep attacks, microsleeps, cataplexy and more in seconds Keep a clinical sleep diary β bedtime, sleep onset, awakenings, efficiency β auto-filled from Apple Watch sleep Track medications, including extended-release, with reminders and an intake planner Plan smart power-naps right before your dips Driving mode: tighter monitoring, earlier warnings and break reminders Export a clear report for your doctor Practical guides for everyday life with narcolepsy Private by design: Your data stays on your device. The model runs entirely on iPhone. Important: This app is a self-tracking and organization tool. It is not a medical device and does not provide a medical diagnosis. Risk estimates are guidance based on self-observation and wearable data β not a substitute for professional medical advice. Never rely on the app alone for decisions about driving or treatment; always consult your doctor.
