A:AnswerYes usually that’s what it means. You can always make sure and ask if there was anything wrong with the phone/ why it was returned. Also ask to look at it before buying and the return policy on the item in case you find anything later. Sometimes they’re okay with that.
A:AnswerIt can in a way. You can use a Bluetooth blood pressure device that pairs with the apple health. No apple watches currently do blood pressure. There are a few that do as far as smart watches but none of them are as accurate as a dedicated blood pressure device.
A:AnswerIt comes with a wall charger that has a 3 foot long charging cable on the end of that cable is the small round magnetic disc that magnetically attaches to the back of the watch face and charges the watch.
A:AnswerSo far I haven’t had any allergies from the metal. Also you can change out the bands to something more comfortable. The back part of the watch the lays on your wrist isn’t metal.
A:AnswerNo it does not. You can pair it with a Bluetooth enabled blood pressure monitor and pair it to the Apple Health App. They have a list of ones that are compatible.
