A:AnswerMy skin is very sensitive and I can't use products with nickel. So far I've had no allergic reactions wearing this watch and I've had it for 3 months.
A:AnswerYes it does have dates available. You can change to different clock faces with some having the day and date next to the time. I love having mine while running around in the er. No more digging my phone out while in the patients room to time and date specimens
A:AnswerYes, a smartphone is much preferred although it is true the screen seems pretty nice. The smarthone provides a blue tooth connection that allows you to download the data that has been tracked. And the Smartphone app is where you really get the ability to review and understand the information the fitbit has been gathering. Using the fitbit ulta without a smartphone would leave you missing out on most of the neat functionality.
A:AnswerNone of them track blood pressure. The Alta HR will track heart rate.
No device out there will you be able to wear to "track" blood pressure throughout the day. To monitor blood pressure you will have to sit down and put the blood pressure cuff on your arm to inflate to get a reading. You can buy automatic blood pressure machines to use in-home so you don't have to go to the doctor just to read your blood pressure.
A:Answercharger comes with it. i have looked at bands on amazon and found them to be reasonable (less than 20 dollars) but the pink band with the rose gold that comes with it is very pretty.
