Documentation is non-existent for this "smart" watch (the little bit they provide is 6 point type, broken english, and more just "what colors are available" than anything useful to setting up your watch). The QR code for set up is literally 1/8 square (no QR code reader I know of will be able to make any sense out of that). No documentation online (best I could find, the company doesn't have a web site). I am not technically incompetent (quite the opposite) and couldn't get it to ever do more than "pair." Am returning it to Amazon. https://smile.amazon.com/OURSPOP-Bluetooth-SmartWatch-Monitor-Message/dp/B077PBFL5H/ref=pd_rhf_dp_p_img_2?_encoding=UTF8&psc=1&refRID=FN9S7DPH1NESBZ5G3P5E #RankBoosterReview #OURSPOP
