A:AnswerYes and No. Most Fitbits do, including this one. I don't trust it, though. Most Fitbits overestimate your heart rate when you move, resulting in overestimating calorie burn. I haven't found an fitness band that uses this "light-based" pulse-detection methodology that measures accurately.
A:AnswerYea it has the Pandora app, you can store songs in offline mode when you're not connected to your phone and pair with some Bluetooth headphones
A:AnswerI don't know your phone specifically, but if it has Bluetooth capabilities and you can install the fitbit app from your phone's app store then you should be good to go. You can always check on fitbit's website for supported devices.. l believe it's found under their support page.
