4iiii unveils Viiiiva heart rate monitor that wirelessly links to your iPhone
 

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. That'll let you add those indicators to sportwatches from the likes of Garmin or Timex through the ANT+ interface, or iPhones and iPods using Bluetooth. To lighten your training load, you can record the data with the Viiiiva alone, then sync it up later and record, plot and analyze your stats with a clutch of iOS fitness apps like Strava or Training Peaks. 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.
