There are quite a few heart rate monitor fitness trackers coming soon to the market.  I'm sure many of us (including me) are anxiously awaiting something that can accurately measure calorie expenditure, rather than relying on a pedometer.  Obviously, nobody wants to have to inconveniently strap a heart rate monitor around their chest.

Here are some options you may keep your eye on for releases in the near future:

 - [Atlas Fitness Tracker][1] $160 USD
 - [Amiigo Fitness Band][2] $99 USD
 - [The Dash In-Ear Smart Headphones][3] $199 USD
 - [Samsung Gear 2 and Gear Fit][4] $199 USD

Already on the market are some other watches/wristbands that might suit your needs, such as:

 - [TomTom Runner Cardio][5]
 - [Mio LINK Wristband][6]
 - A cursory google search should yield quite a few other options in this department.

And maybe somewhere way down the line, you'll be able to have a smart contact lens that watches your heart rate as well, such as:

 - [Google Smart Contact Lens][7]
