A:AnswerI did see stock market apps. i am not using them so I do not know if you can buy and sell with it. I suspect its only for monitoring the stock market.
A:AnswerYes it does, i use it for my heart rate and steps, and it does both pretty accurately. It does a ton of other stuff but those two seem the most relavent to your question.
A:AnswerThe watch works with android and apple phones. Works best with samsung phones but reviews indicate it does work well with other android phones. Very nice item.
A:AnswerIt can, but word of caution, the heart rate monitor is not the most accurate. If that is one of your priorities, then I'd recommend a Fitbit over this.
