I own this. It doesn't connect via Bluetooth or need an app. The idea is that it cools your forehead and slows your metabolism. I find it useful, I can't sleep with it on because it makes some noises which bother me (but I am very sensitive).
Sorry, there was a problem. Please try again later.I just submitted a review that should help with those questions. The only thing I didn't mention is that the cooling function pulses/rolls in and out. The cooling sensation lasts for around 10 seconds and then off for 10 seconds and so on. Hopefully, the rest of your answers can be found in my review when BB posts it. Hope that helps!!
Sorry, there was a problem. Please try again later.the charge lasts all Nite. about 8 hours or so. it is not Bluetooth. It can help as it keeps cool. Basically, you place it on your head like a headband. it has a cord that comes off the top and you can place that on either side and that is connected to a remote that you can control the temp.
