Sleep sounds + CBT-I routine

Features & Capabilities

Protocol Zero is the first Active Sleep Improvement app based on research. It provides a clear, personalized daily plan so you know exactly what to do to sleep better starting tonight.

New: Sleep sounds you can play at night (white noise, brown noise, rain, and calming audio) integrated with your personalized CBT-I routine. It acts as your personal sleep coach, guiding wake times, morning light exposure, caffeine cutoffs, and wind-down mode to relax before bed. The app uses science-backed CBT-I techniques to help you fall asleep faster and wake refreshed. Note: it’s an educational tool (not a medical device); in-app subscription is required to use Protocol Zero.

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
