Just wanted to do an update on what life was like without my Apollo Neuro after living with it for almost a year and then not having it for 10 days. Lets just say that I did not sleep well. I don’t know how to explain it. I couldn’t wait to get it back. I would also wear it sometimes during the day. It would help me concentrate and lower stress. It uses some sort of haptic engine. I find the vibrations on my iPhone pretty cool. This is a similar concept just with more control. I usually wear on my left wrist for sleep and on the inside of my ankles during the day.
