A:AnswerI haven't seen any directions as to how to get the time to stay on. However if you have the Fitbit app or connected to a computer you can set it to where you just double tap the screen/body area and it can display time, steps, heart rate or miles depending on what you set it up for.
A:AnswerThis Fitbit is great asset for a kid; it's easy to track results; there is a lot of tracking information on the Fitbit app; a kid can choose what information will benefit their goals; with adult guidance, this Fitbit could prove to be a great learning experience for the kid.
A:AnswerWhen mine became loose, I started using a narrow velcro band - like one you use to hold computer cables together. That worked great for an interim latch.
A:AnswerI have compared the heart rate monitor with an exercise bike HR monitor and with my blood pressure cuff device. In all cases, they read the exact same value. As far as the sleep monitor goes, it is scary how accurate it is. The steps are a little off, but more accurate than other tracking devices that I've used.
