Protocol Zero is the first Active Sleep Improvement based on Research
It’s a system that gives you a clear, personalized daily plan so you know exactly what to do to sleep better starting tonight.
New: Protocol Zero now includes sleep sounds you can play at night, including white noise, brown noise, rain, and calming audio. Use them alongside your personalized nightly routine to unwind faster and fall asleep more easily.
YOUR PERSONAL SLEEP COACH
Unlike most apps that only track your sleep, Protocol Zero guides you through a daily schedule designed to reset your body clock and improve your sleep quality. Each day, you get specific actions that make a real difference:
- Set a consistent wake time and get morning light exposure to reset your internal clock and help you feel alert during the day
- Follow precise caffeine cutoffs so late-day coffee or tea never interferes with your deep sleep
- Activate wind-down mode in the evening, which blocks distracting apps and helps your mind and body relax before bed
- Practice science-backed techniques from Cognitive Behavioral Therapy for Insomnia (CBT-I), proven to help you fall asleep faster and stay asleep longer
HOW IT WORKS
Your body depends on a 24-hour internal clock to regulate sleep. Protocol Zero anchors your day around two key signals: when you wake up and when you get morning light. The app then schedules your caffeine, meals, exercise, and wind-down activities into optimal time windows. This structure helps you build habits that make you naturally tired at bedtime, so you fall asleep more easily and wake up refreshed.
No more lying awake wondering what went wrong. No more generic sleep tips that never stick. Protocol Zero gives you a clear, automated plan that builds lasting habits for deep, restorative sleep.
SIMPLE, SCIENCE-BACKED, AND ACTIONABLE
Protocol Zero combines the most effective techniques from CBT-I the gold standard for sleep improvement with modern behavioral science. Research shows that tracking your habits and making targeted changes leads to real, lasting results. We make these techniques simple to follow, so you can start seeing improvements right away.
WHO IT’S FOR
Protocol Zero is designed for healthy adults who want to optimize their sleep. It is an educational tool, not a medical device, and is not intended to diagnose or treat sleep disorders. If you suspect you have insomnia, sleep apnea, or another medical condition, consult a physician.
Stop guessing about your sleep. Start following a clear plan and experience better rest tonight with Protocol Zero.

Really well designed and easy to use. It focuses on the sleep habits that matter most and the science behind it makes sense. When I follow the routine I feel better in the mornings.

First time
TheFoxHasOpinions
Only going w/3 stars since I haven’t actually had a chance to use it for sleep yet.. Mainly wanted to add some info the app doesn’t ask… My current answers are impacted by 3 major things: First, I was discharged from hospital 2 days ago after emergency surgery to keep me alive, Second, I’m still on 8+ meds to try and win the postoperative pain and several others to prevent my reason for nearly dying from doing a repeat before I’ve even healed from the first time, and Third, I have Neurological Lupus which in and of itself puts me behind the 8ball even without the postoperative issues. I really think this app could be an excellent resource if yall added factors that are out of our control to the basic algorithms.I’ll be back to update depending on how the app does in the next few days/weeks/whatever
