A:AnswerYes. You can look at the app on your phone to see your daily step count. You will also get a weekly email from Fitbit showing your weekly stats, including steps for each day.
A:AnswerYes you can share information. Also multiple extra paid software programs available that appear to provide this service as well. I did not pay for any though
A:AnswerIt says the same thing for the Versa but as soon as I got into the pool and started swimming, the face opened up and it fried the watch. So no, I would not trust the Charge 3 or 4 either for the swimming exercise.
You can probably take a shower with it and go in the rain, but not swimming, even though it has swimming in the exercise. What I do, I add swim and I put how many minutes I did it and it will give you the calories based on that.
