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

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.
