I just ordered the bundle. Want to make sure that my pacemaker is working properly. And, mainly want the sleep apps. I have neurological sleep apnea, from a brain tumor squeezing my medulla, autonomic nervous system, for up to eighteen years. Also, have some pre-existing obstructive apnea, since 1999. I now have a bi-pap with a ventilator feature that automatically responds to apnea events. Want to make sure that it’s working as it should, along with the quality of my sleep. If something isn’t working well, the pulmonologist may be able to adjust settings. The sleep features are very important to me.Also, does the watch come with a charging cord? If not, will a flat round apple charging cord work? About how long till I receive the watch and with which carrier?Thank you so very much. I look forward to receiving your product.
