Yes. On the Nike Fuelband SE, you can press the button twice to display the time.
FitBit trackers are water resistant, not water proof. That means, they can get rained on when you are outside or have some water splashed on it, if you are around a pool perhaps. However, it's not recommended that you shower or swim with your FitBit. Even though a little bit of water won't harm the device, a lot of it can cause harm. Additionally, if you a person who never takes your FitBit off, taking it off when you shower is a good time to do so, since you aren't getting that many steps. It's very important to give your hand a break!
You can take a FitBit into the ocean for a small amount of time. However, the salt could hurt the FitBit if used for long periods of time.
The firs time the FitBit is charged it can take up to 4 hours to charge the battery completely.
flex time
Fitbit was created in 2007.
The Fitbit Charge HR adds a Heart Rate monitor (that is what the HR stands for).
No, the Fitbit Zip does not have a dedicated sleep tracking feature. It primarily focuses on tracking steps, distance, and calories burned. For sleep tracking, you'd need to use a different Fitbit model, such as the Fitbit Charge or Fitbit Inspire, which have built-in sleep monitoring capabilities.
With the Fitbit Flex, you have to tap it 5 times to enter sleep mode and then 5 times in the morning to take it out. This helps it to track how long you slept for. To work out how many times you wake up and how well you've slept, the accelerometer tries to detect any major movements during the night. Tossing and turning implies a poorer quality sleep.
No. Only the one that came with that FitBit.
The Fitbit Blaze was officially released in March 2016. Since then, it has been discontinued, and Fitbit has introduced newer models in their lineup. If you're looking for a current Fitbit device, it's best to check their latest offerings on their official website or retailers.
Ummm... tell them not to flex that specific muscle...
Lack of coverage could be an issue with flex time unless people's schedules are staggered enough that someone is always available.
