I just downloaded tonight! Geez! Give me a few nights!!

First time

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

Response from developer

We’re glad you were able to integrate the protocol in just three days—wow! Since you no longer want the subscription, we can help you request a refund from Apple. If you tap Support in the app’s Settings, it will automatically provide us with the information we need, and we can continue the conversation there.

Finally a sleep app that makes sense

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.

Better than Melatonin

I’ve worn an Oura ring for two years, but seeing the data never actually changed my habits. This app has helped me get the best sleep EVER. I’m finally falling asleep naturally without needing melatonin. Simple, tough, but it works

Response from developer

Thank you so much for sharing your experience. We're thrilled to hear that Protocol Zero has helped you achieve natural, restful sleep and lasting habit change. Your feedback motivates us to keep improving and supporting your sleep journey.
