It can also set heart rate monitoring 24 hours a day on the APP.and temperature measurement interval. I use it every day to record steps and exercise status, but I don't know about these functions. Open the APP, you will be pleasantly surprised, this watch is good. My watch can also play music or related voices on any mobile APP, like a small external speaker. You need to pair the two Bluetooth [HT5] and [HT5-aUDIO-31E] at the same time to use the functions of playing music and making calls. Not only can you make calls via Bluetooth, but you can also take photos with your mobile phone. My girlfriend likes it very much. After adjusting the angle of the mobile phone and pressing the watch, you can achieve a perfect long-distance selfie. The permissions in the APP must be turned on to use this watch perfectly. Using it with APP can better reflect its value. Recommended.Great watch for tracking fitness. Comfortable to wear, all the features I wanted. Had an issue with it not working just a couple of weeks after purchase and the service department was helpful at trying to get issue resolved. ?Yes I would recommend!See aboveThe instructions are for those with 20/20 vision. The blood pressure is not accurate at all. I have a blood pressure cuff of my own and it was accurate after medication and this watch had me have one foot in the grave lol. I'll update if this improves anything.Wrong information on heart blood pressure and difficult to set up.This fitness tracker has exceeded all of my expectations .The OS seems responsive and it’s easy to slide through different modes. Pretty cool. Battery life is much better and you only need to charge it once a week instead of everyday.
