My experience with the Apollo Neuro has been awesome. I’ve had trouble sleeping for years. You can wear it on your ankles or your wrists. During the day I’ll wear it on my ankles and during the night I put it on my wrist. For sleep I turn it on and it will stay on for two hours. If I wake up I turn it on again and I go right out again. So this works fantastic. During the day if I’m feeling stress I just put it on my ankle. I can control it with my cell phone. It does help me relax and the battery lasts all day.
I’m not sure how to describe it but you can feel the vibrations over your whole body. It’s very calming.
It was developed by neuroscientists. It helps with HRV or heart rate variability thus helping with the fight or flight mechanism.
