My ideal Fitness Tracker:
1) I don't want to spend more than $200, but I will if the device is multifunctional.
2) I personally don't need another screen for email when I'm running because I don't want to think about work. So the display can notify me of a message, but I don't want to be able to read it.
3) The heart rate sensor has to be accurate and measure 24/7.
4) The device must relay all the information to an app on my iPhone and/or the cloud .
5) A long battery life is important
The first fitness tracker that I looked at is the Fitbit Flex Wireless Activity + Sleep Wristband
I love the look of the device. It has no display but multiple sensors.

However, the Fitbit does not have a continuous heart rate monitor. So it's not for me.
The 2nd one I considered was the Adidas Fit Smart. A strong point was that it did have an app that relayed your heart rate, however the battery life is only 10 hours.

The third fitness tracker was the Samsung Gear Fit. It had a good battery life (2-3 days) and heart rate monitor. However, it was out of the running because it doesn't work with the iPhone.
So, I think I'm just going to wait for the Fitbit Surge next year.
