A:AnswerYes I do have one, it's a LifeSource. LifeSource does both and it is very accurate and not expensive. Since I have been using my Fitbit my blood pressure went from 200/90 to 127/77.
A:AnswerIt would depend on which vivo3 you're looking at. The vivofit 3 is compatible with a HR monitor strap. The vivosmart 3 is not compatible with a HR monitor strap.
