4iiii unveils Viiiiva heart rate monitor that wirelessly links to your iPhone or smartwatch
So, you’ve been monitoring virtually every aspect of your athletic performance and tweeting it to the world, but not your heartrate or other basic performance factors? Apparently that just won’t do, sport-o, so 4iiii has announced the chest-worn Viiiiva monitor.

You’ll be able to pick one up soon for $ 79 on at 4iiii’s site (see coverage) and select retailers, so head to the PR after the break and feel the burn.
