A:AnswerNo. Not that I have found. However you can do a small heart rate EKG clip to save and graph and/or send to your dr. There is also a specific blood sugar monitor that you can link with it.
A:AnswerNo, most of the standard data and metrics are available without premium, it's just the deeper level details that is provided by premium. I believe it comes with a 6mo trial of premium though to see the difference.
A:AnswerYes you can talk and even switch the call back to your phone if you want. You can either choose Google assistant or Alexa. But I think that Google assistant is the only way to talk and receive calls.
A:AnswerI put mine on charge at night when I shower. It goes to 100% in a very short time. Days when I didn't charge it when on a trip it was good for several days. I have a charging block I use and the only problem with it I have to wiggle the wire around to getting it charge. I can tell its charging when block lights stay on. Also on the fit bit app on my phone can slide your finger down from the top of the screen and the battery life of the sense magically opens up and shows how much charge it has. Over a year and still working great.
